Additional aspects, features, examples and embodiments are described in more detail below.
Certain compositions and articles are described below with reference to the accompanying figures in which:
Certain embodiments described herein may comprise a surface coating disposed on at least some portion of an underlying coating or underlying electrodeposited coating. The presence of the two or more coatings can provide desirable attributes including enhanced retention of the surface coating, anti-corrosion properties, hydrophobicity and other properties and combinations of these properties. The exact materials present in the various coating layers and substrate layers may vary and illustrative materials are described in more detail below. For example, the coating may comprise (i) at least one refractory metal, at least one refractory metal oxide or at least one other compound comprising a refractory metal and (ii) at least one transition metal, at least one transition metal oxide or at least one other compound comprising a transition metal.
In some instances, one or more additional coatings can be present between a coating, e.g., an electrodeposited coating, and a surface coating or between the coating and the substrate or between any two of the coatings or layers described herein. If desired, two different types of surface coating materials can be deposited or co-deposited onto the coatings, e.g., can be deposited into electrodeposited coatings. Illustrative types of surface coatings, electrodeposited coatings, substrates and articles are described in more detail below, and additional surface coatings, electrodeposited coatings, substrates and articles will be selected by the person of ordinary skill in the art, given the benefit of this specification. While various surface coatings are described as comprising certain materials, the surface coatings are generally the reaction products which result after addition of the surface coating material to an underlying substrate or coating.
In some instances, the term “layer” is used in place of, or in addition to, the term coating. Where the coating comprises multiple different materials, the various materials may be referred to as being present as layers in the coating to increase the overall clarity and facilitate an easier description of the various materials present in the coatings. The layer need not cover an entire surface of the substrate and may instead only be present on certain areas of portions of the substrate. An interface typically is present between layers as a distinguishing feature that separates two or more layers.
Surface Coatings
In certain examples, the surface coatings used on the articles described herein typically comprise one or more silane, silanol or silicon based groups that are functionalized to permit reaction with the underlying electrodepositing coating. These materials are collectively referred to herein as a “silane system.” As noted herein, the surface coating can be produced by exposing a surface of a substrate or another coating to one or more silane, silanol or silicon based groups that are functionalized to permit reaction of the one or more silane, silanol or silicon based groups that are functionalized with the underlying substrate and/or any underlying coating. For example, the functionalized groups may comprise one or more side chain functionalities which can form a covalent bond with one or more of the transition metal species present in the substrate and/or electrodeposited coating. A generalized structure of one suitable material is shown in
In some instances, the silane system used to provide the surface coating may comprise one or more epoxysilane groups such as the generalized epoxysilane shown in
In certain examples, the surface coatings described herein may comprise, or be produced using, one or more water-soluble aminopolysiloxanes. Such aminopolysiloxanes can be produced, for example, by hydrolytic polymerization of a functionalized aminosilane salt followed by further functionalization with a functional alkyl salt. For examples, an aminosilane can be combined with a solution comprising an alkyl salt in an organic solvent to provide the functionalized aminopolysiloxane. In some examples, a mixture of 3-aminopropyltrialkoxysilane and bis(trialkoxysilylpropyl)amine in alcoholic solvents can be used to provide the aminopolysiloxane. In other examples, an aqueous solution of a water-soluble aminosilane and an alkyltrialkoxysilane can be combined to provide an aminopolysiloxane. In some instances, mixing of water-soluble aminoalkylalkoxysilanes with alkyltrialkoxysilanes and/or dialkyldialkoxysilanes can provide organopolysiloxane-containing compositions. In certain instances, aminoalkyltrialkoxysilanes and bissilylaminosilanes can be combined to provide an aminopolysiloxane. In some examples, bissilylaminosilanes and/or bissilylpolysulphanes can be combined in aqueous alcoholic solutions to provide an aminopolysiloxane. In certain embodiments, reaction products of aminosilanes which also contain small amounts of tris(trialkoxysilylpropyl)amines can be produced in alcohol solutions. While not required in every application, aminopolysiloxanes desirable for use in the surface coatings described herein may be stable up to about 600 degrees F. or more.
In other instances, the surface coating may be or may comprise, or be produced using, a silylakylamine such as those described in U.S. Pat. No. 8,889,812. For example, silane systems based on tris(alkoxysilylalkyl)amines can be used to provide a surface coating. In some examples, the silane systems may be substantially free or organic solvents and generally be water soluble to permit deposition without the use of toxic or harmful solvents. While not required in every application, silylalkylamines and alkoxysilylalkylamines desirable for use in the surface coatings described herein may be stable up to about 600 degrees F. or more to permit their use in high temperature applications where corrosive materials or gases might be encountered.
In certain examples, the surface coatings can be produced using a silane system comprising tris-silylated amino-functional silicon compounds and water, especially as a sol-gel system or an aqueous based solution. While not absolutely true in every case, tris-silylated amino-functional silicon compounds generally comprise amino compounds wherein at least one amino group having three silyl groups bonded to the nitrogen is present in one molecule. The silyl group in question is generally bonded to the nitrogen center by a bivalent alkyl unit, for example —CH2—, —(CH2)2—, —(CH2)3—, —CH2[CH(CH3)]CH—, etc. In addition, the silyl groups may independently be the same or be different and, as well as “Si—OH” and/or “Si—O—Si” units, optionally have further functionalities, especially organo-functionalities or fluoro-functionalities.

In certain examples, the surface coating materials described herein can be produced, for example, by mixing a siloxane, organosiloxane, aminosiloxane, siloxane precursor, or aminosiloxane precursor (or combinations thereof) with water, and a catalyst to promote a sol-gel reaction to form a solution having particles. If desired, the sol-gel reaction can be performed without using any organic solvent. Chemical modification of the resulting particles can be performed, for example, by reacting a hydrophobic agent with the particles to provide surface-modified particles. If desired, a surfactant can be added to the surface-modified particles to provide a surface coating material that may be hydrophobic depending on the particular surface modifications performed. The siloxane precursor may comprise, for example, one or more —SiOR or —SiOH functional groups, wherein R is CnH2n+1, and n is a positive integer. In some instances, R may comprise at least one fluoro group or at least one amino group or both.

In some examples, one or both of the organofunctional silane and functionalized silicon dioxide particles may comprise a silanol group as noted generically in
In some instances, the surface coating may be a fluorine containing material as described for example in WO2017/112724, e.g., may be or may comprise hollow poly(vinylidene difluoride) microspheres. Additional fluorine containing materials such as polytetrafluoroethylene and other fluoropolymers may also be present as part of the materials used to provide the surface coating.
In some configurations, the surface coating is typically disposed on the textured coating using a non-electrodeposition process, such as, for example, spraying, brushing, dipping, spreading, jet coating, sol gel processing or other processes. In some examples, the average particle size of the surface coating, prior to disposition, may be about 50% less, 40% less, 30% less or 25% less than a first size, e.g., the average characteristic length, of the microstructures of the electrodeposited coating. For example, an electrodeposited coating (or other coating) may be electrodeposited onto the substrate, and SEM images or other suitable techniques can be used to determine an average characteristic length of the microstructures of the electrodeposited coating. The average particle size of the surface coating materials to be applied to the electrodeposited coating may then be selected to be less than the average characteristic length of the microstructures. Without wishing to be bound by any particular application method, a dispersion of particles comprising the surface coating material is typically produced. This dispersion may comprise an aqueous carrier, an organic carrier or mixtures thereof as desired to permit application of the surface coating material to the electrodeposited coating. Post-application of the surface coating material, the article can be subjected to other treatment steps including, but not limited to, drying, heating, cooling, blotting, annealing, tempering, consolidating, sanding, etching, polishing or other physical or chemical steps.
In some examples, an additional layer of material can be applied to the applied surface coating if desired. In other instances, the electrodeposited coating, the surface coating or both may each comprise one or more additional materials such as a polymeric material. The additional material (or additional layer) can include, but is not limited to, organic polymers, thermoplastic polymers, thermosetting polymers, copolymers, terpolymers, a block copolymer, an alternating block copolymer, a random polymer, homopolymer, a random copolymer, a random block copolymer, a graft copolymer, a star block copolymer, a dendrimer, a poly electrolyte (polymers that have some repeat groups that contains electrolytes), a poly ampholyte (poly ampholytes are polyelectrolytes with both cationic and anionic repeat groups.

In certain embodiments described herein, the electrodeposited coating may comprise one or more textured layers. For example, the electrodeposited coating may comprise one or more layers which may comprise various features. In some instances, the coating may comprise at least one textured layer comprising a metal or metallic compound or a transition metal alloy comprising one, two, three or more different transition metals. In certain configurations, the textured layer can provide, at least in part, a hydrophobic surface comprising a plurality of surface features in the micro or nano size range. The size of the surface features can be defined based on their largest characteristic length. Some textured layers comprise surface features in the range of 5 to 15 micrometer. Others comprise surface features in the range of 0.5 to 1 micrometer. In some examples, the surface features are positioned within at least at two different surface planes with different heights in regard to an arbitrary zero reference point. In other instances, the features can be packed closely together with negligible, substantially no space or no space between adjacent features compared to the overall size of the features. In certain examples, the coating may comprise at least one textured layer with one or more of the following characteristics with respect to the arrangement of the surface features, composition, and hydrophobic characteristic of the textured layer.
In certain examples, the textured layers when present may comprise at least one metal or metallic compound or metal alloy. Examples of some of the metals which can be used include, but are not limited, to Nickel (Ni), Zinc (Zn), Chromium (Cr), Copper (Cu), Zinc/Nickel alloy (Zn/Ni), Zinc/Copper alloy (Zn/Cu), Nickel/Molybdenum (Ni/Mo) alloys and other transition metals and combinations thereof. In some examples, the textured layer comprises a transition metal alloy comprising nickel and at least one other transition metal, e.g., Nickel and at least one of Scandium, Titanium, Vanadium, Chromium, Manganese, Iron, Cobalt, Copper, Zinc, Yttrium, Zirconium, Niobium, Molybdenum, Technetium, Ruthenium, Rhodium, Palladium, Silver, Cadmium, Hafnium, Tantalum, Tungsten, Rhenium, Osmium, Iridium, Platinum, Gold, Mercury, Rutherfordium, Dubnium, Seaborgium, Bohrium, Hassium, Meitnerium, Darmstadtium, Roentgenium, and Copernicium with stable and non-radioactive transition metals being desirable. In certain examples, the textured layer comprises a transition metal alloy comprising zinc and at least one other transition metal, e.g., Zinc and at least one of Scandium, Titanium, Vanadium, Chromium, Manganese, Iron, Cobalt, Nickel, Copper, Yttrium, Zirconium, Niobium, Molybdenum, Technetium, Ruthenium, Rhodium, Palladium, Silver, Cadmium, Hafnium, Tantalum, Tungsten, Rhenium, Osmium, Iridium, Platinum, Gold, Mercury, Rutherfordium, Dubnium, Seaborgium, Bohrium, Hassium, Meitnerium, Darmstadtium, Roentgenium, and Copernicium with stable and non-radioactive transition metals being desirable. In other examples, the textured layer comprises a transition metal alloy comprising Copper and at least one other transition metal, e.g., Copper and at least one of Scandium, Titanium, Vanadium, Chromium, Manganese, Iron, Cobalt, Nickel, Zinc, Yttrium, Zirconium, Niobium, Molybdenum, Technetium, Ruthenium, Rhodium, Palladium, Silver, Cadmium, Hafnium, Tantalum, Tungsten, Rhenium, Osmium, Iridium, Platinum, Gold, Mercury, Rutherfordium, Dubnium, Seaborgium, Bohrium, Hassium, Meitnerium, Darmstadtium, Roentgenium, and Copernicium with stable and non-radioactive transition metals being desirable.
In certain configurations, the textured layers of the electrodeposited coatings may provide hydrophobic characteristics without any additional chemical treatment. It is worth mentioning that certain physical treatments may be performed to make the textured layer hydrophobic. For example, a water contact angle of greater than 90° can be provided by the electrodeposited coatings either alone or after being used with the surface coatings. In addition, a superhydrophobic coating is defined as a coating which provides a water contact angle of more than 150°. Water contact angle can be measured using contact angle measurement equipment based on the ASTM D7490-13 standard. This angle is conventionally measured through the droplet, where the water-air interface meets the solid surface. A Kruss-582 system can be used to obtain the contact angle data.
In certain embodiments, the electrodeposited coatings, when used in combination with a surface coating, can provide an overall coating that can be considered mechanically durable. Mechanical durability can be defined based on two criteria of hardness and pull-off (tape) tests. The hardness criterion is defined based on the pencil hardness level of more than 3B corresponding to the ASTM D3363-05(2011)e2 standard measurement. This test method determines the hardness of a coating by drawing pencil lead marks from known pencil hardness on the coating surface. The film hardness is determined based on the hardest pencil that will not rupture or scratch the film. A set of calibrated drawing leads or calibrated wood pencils meeting the following scales of hardness were used: 9H-8H-7H-6H-5H-4H-3H-2H-H-F-HB-B-2B-3B-4B-5B-6B-7B-8B-9B. 9B grade corresponds to the lowest level of hardness and represents very soft coatings. The hardness level increases gradually after that until it gets to the highest level of 9H. The difference between two adjacent scales can be considered as one unit of hardness.
In addition to the pencil hardness, durability of the coatings can be characterized using the standard ASTM procedure for the tape test (ASTM F2452-04-2012). This attribute of durability is defined based on exhibiting at least level three of durability among five levels defined by the standard test. In this test, a tape is adhered to the surface and pulled away sharply. The level of the coating durability obtained based on the amount of the coating removed from the surface and attached to the tape. The lowest to highest durability is rated from 1 to 5, respectively. A lower rating means that some part of the coating was removed by the tape, and therefore, a part of the coating functionality was lost. Rate 5 corresponds to the condition that zero amount of coating is removed. Therefore, the functionally of the coating at this rate remains the same after and before the tape test.
In addition to the pencil hardness and tape tests, a Tabor abrasion test is another test that can be performed on the coatings described herein. In this test, the coated samples can be subjected to several cycles of abrasive wheels with 500 g loading weight at 60 rpm speed. The mass loss percentage (%) of the coatings can then be calculated for each individual sample based on the ratio of mass loss to the initial mass of the coating.
In some embodiments, the coatings described herein may be considered easy-clean coatings. Easy-clean characteristic is defined, wherein in a cleanability test, at least 80 percent of the surface can be cleaned. In this test, the coating is painted with cooking oil and placed in an oven at 100° C. for 12 hours. It will then be wiped out with a wet tissue. Easy-clean characteristic is also related to the coating oleophobicity. The oleophobic characteristic can be measured by the contact angle of oil on a surface.
Certain configurations of the coatings described herein can also provide one or more of the following attributes: reduce transfer from/to the surface, provide protection, prevent or discourage adhesion of water and microscale/nanoscale objects, or a combination of said functionalities. Certain coatings can be used in many different applications including but not limited to, wetting, dirt accumulation, corrosion, microbial adhesion and disease transformation, ice formation, friction and drag and biofouling prevention and/or mitigation. For instance, the coating can protect, to at least some degree, an article, e.g. vehicle or other components, against detrimental effects of the environment, e.g. corrosion and fouling, which reduce the overall useful lifetime of the article or cause fading or deterioration. The coating can be used in equipment with high-temperature working conditions such as ovens, heat-exchangers, and condensers. It can be used to mitigate sticky problems at high temperature environments. As another instance, certain configurations of coatings can discourage transfer of liquids, dirt, microorganisms, viruses, or particles from/to an article to/from human and animals upon contact, which can reduce cross contamination.
Without wishing to be bound by any particular theory, certain configurations of the coatings disclosed herein can work by trapping some of the surface coating materials between the structures of the surface texture. Other surface material may remain on top of the surface texture. Some part of the macroscopic object can be in contact with the media and not the surface. As a result, compared to uncoated surfaces, transfer between the macroscopic object and the coated surface is discouraged. Macroscopic objects include, but are not limited to, liquid droplets, a part of a human or animal body, tools, food, oils and solid objects.
In certain instances, the coatings can enable protection against undesirable consequences of contact between the surface and the macroscopic, microscale and/or nanoscale objects such as equipment damage, corrosion, transfer of germs, dirt, and smudge, friction and drag. In other instances, fluids may not stick to the coating surface. Liquids for example can be water, sea water, oil, acids, bases, petroleum products, aqueous solvents, organic solvents or biological fluids such as blood and urine. In this example, liquid drops bead up on the coating surface, roll off the surface with a slight applied force, and bounce if dropped on the surface from a height. In fact, the overall coatings can provide articles that can be considered super-repellent (e.g. superhydrophobic and/or superoleophobic).
In certain examples, the electrodeposited coating can enhance adhesion of the surface coating. In other instances, a plurality of individual microstructures of a first size, e.g., the microstructures may comprise an average diameter of 15 microns or less, or 10 microns or less or 5 microns or less or 0.5 microns or less may be present in the electrodeposited coating. The surface coating can comprise particles or materials with an average size less than the first size of the microstructures of the electrodeposited coating. In some examples, the surface coating can comprise both particles or materials with an average size less than the first size of the microstructures of the textured coating and particles or materials with an average size greater than the first size of the microstructures of the electrodeposited coating. For example, the adhesion or pull-off strength of the surface coating may be 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80% or even 90% higher when the electrodeposited coating is present compared to the pull-off strength of the surface coating being disposed on a substrate not having the same electrodeposited coating. As discussed herein, pull-off strength can be tested, for example, using ASTM D4541-09. In some configurations, the pull-off strength of the surface coating, when the electrodeposited coating is present, may be at least 200 psi, 225 psi or 250 psi as tested using ASTM D4541-09. In some examples, the electrodeposited and surface coatings can be present as distinct layers with a defined interface, whereas in other instances, the coating materials may infuse or penetrate into each other without a discernible interface between them.
In certain configurations described herein, the electrodeposited coating can be configured as a porous coating (to at least some degree) to permit the surface coating material to penetrate or infuse into the void space of the electrodeposited coating. For example, there may be space between microstructures of the electrodeposited coating and/or space within the microstructures themselves that permits the surface coating material to infuse, enter or penetrate into the electrodeposited coating. Infusion or entry of the surface coating material into the electrodeposited coating can reduce the overall surface roughness, e.g., the surface roughness once the electrodeposited coating has been disposed on the article is much higher than the surface roughness once the surface coating has been disposed on the electrodeposited coating. As noted herein, the electrodeposited coating and surface coatings can each be applied in numerous manners including, but not limited to, electrodeposition, brushing, spraying, dip-coating, jet coating or other methods.
In some examples, the microstructures of the electrodeposited coating may comprise a first size, which refers to the largest characteristic length of the surface features. Where the microstructures are generally spherically shaped, the largest diameters of these spheres can be defined as the first size of the surface features. The surface features of the electrodeposited coating can be desirably positioned at least at two different surface planes with different heights in regard to an arbitrary zero point. While not wishing to be bound by this example, there can be negligible space between adjacent surface features compared to the size of the features. After coating of the electrodeposited coating with the surface coating, substantially no open space may exist between the microstructures. This filling of gaps and voids by the surface coating can reduce overall surface roughness, e.g., by 50% or more, and may result in a decrease in the overall porosity of the electrodeposited coating to be close to zero, e.g., less than 5%, 4$%, 3%, 2%, or 1%.
In certain configurations, in addition to the metal, metallic compound or transition metal alloys present in the electrodeposited coating, the electrodeposited coating can comprise other materials as well. For example, the electrodeposited coating may comprise one or more of Chromium Nitride (CrN), Diamond Like Carbon (DLC), Titanium Nitride (TiN), Titanium Carbo-nitride (TiCN), Aluminum Titanium Nitride (ALTiN), Aluminum Titanium Chromium Nitride (AlTiCrN), Zirconium Nitride (ZrN), Nickel, gold, PlasmaPlus®, Cerablack™, Chromium, Nickel Fluoride (NiF2), any Nickel Composite, any organic or inorganic-organic material and combinations thereof. Examples of nickel composites include, but are not limited to, composites of nickel with different particles selected from a group consisting of PTFE, silica (SiO2), alumina (Al2O3), silicon carbide (SiC), diamond, diatomaceous earth (DE), boron nitride (BN), titanium oxide (TiO2), single wall carbon nanotubes (SWCNTs), multi-wall carbon nanotubes (MWCNTs), kaoline (Al2O3.2SiO2.2H2O), graphite, other nanoparticles, or any combination thereof. Examples of organic or inorganic-organic materials include, but are not limited to, parylene, organofunctional silanes, fluorinated alkylsilane, fluorinated alkylsiloxane, organofunctional resins, hybrid inorganic organofunctional resins, organofunctional polyhedral oligomeric silsesquioxane (POSS), hybrid inorganic organofunctional POSS resins, silicone polymers, fluorinated oligomeric polysiloxane, organofunctional oligomeric poly siloxane, fluorinated organofunctional silicone copolymers, organofunctional silicone polymers, hybrid inorganic organofunctional silicone polymers, organofunctional silicone copolymers, hybrid inorganic organofunctional silicone copolymers, fluorinated polyhedral oligomeric silsesquioxane (FPOSS), Dynasylan® SIVO, other similar groups, or any combination thereof. In some instances, the electrodeposited coating can be produced in the presence of the surface coating materials so that some of the surface coating material ends up in the electrodeposited coating.
In some examples, the electrodeposited coating may comprise organofunctional silanes that combine the functionality of a reactive organic group with inorganic functionality in a single molecule. This special property allows them to be used as molecular bridges between organic polymers and inorganic materials.

In some examples, the coatings described herein may provide corrosion resistance to some degree. Damage to the substrate can be caused, for example, by wear, corrosion, high temperature or by a combination of these three factors. For example, the coatings may protect the underlying substrate from degrading or corroding upon exposure to harsh environments such as acids, bases or the like. In addition, the nature of the coatings can provide protection to the substrate even when the coating is scratched, etched or otherwise remove to some degree.
Substrates
In certain embodiments, the substrates that may be present in the articles described herein may be substrates that generally will corrode (to at least some degree), may be heat or chemically sensitive or may degrade to some degree in the absence of a coating or protective layer. The substrate may comprise many conductive or non-conductive materials including, but not limited to, metals, steel, stainless steel, plastics, wood, paper, ceramics or other materials. Where it is desirable to provide an electrodeposited coating on a non-conductive substrate, a conductive primer layer can be provided to the substrate prior to deposition of the electrodeposited coating.
In some examples, the substrate itself may comprise a transition metal alloy, which can permit the omission of the electrodeposited coating or coating adjacent to the substrate. In such configurations, the surface coating materials can be applied directly to the substrate without the need to first apply an electrodeposited coating.
Various specific substrate materials are described in more detail below in connection with the illustrative articles described herein.

In certain examples, the coatings present on the oven surfaces and/or cooktop may provide non-stick surfaces. For example, food residue easily sticks to porcelain enamel coatings, which are used to coat most existing oven cavities and cooktops. Foods are often times spilled upon the surface of oven cavities and cooktops and baked into a hard residue that clings strongly to the enamel coating. The most common technique for removing food residue from oven cavities in residential applications is applying a high temperature cleaning cycle called a “self-cleaning” function. This function applies a high enough temperature for a short time and results in the pyrolysis of the food residue on the surfaces of the oven cavity. A “Self-cleaning” function increases energy consumption of the oven. Moreover, its installation adds to the material and manufacturing costs of the oven appliance. Cleaning of cooktops is even more problematic than oven cavities. Consumers usually need to apply a harsh chemical, a sharp cleaning pad, and a large amount of force to remove food residue from the cooktops. This will often scratch and/or damage the cooktop coating. Due to these problems for cleaning food residue from ovens, there is a great interest in replacing porcelain enamel with suitable coatings in various appliances used for heating. The coatings described herein can provide non-stick functionality to ease cleaning of spills and other residue.

Production Methods
In certain embodiments, the coatings described herein can be produced in many different methods. For example, the surfaces of the substrate can be treated, e.g., etched, abraded, physically or chemically treated, etc., prior to electrodeposition of a coating on the treated surface. Alternatively, the electrodeposited coating can be deposited on the substrate and then the combination can be etched prior to deposition of a surface coating. In other instances, substrate surfaces can be etched and a transition metal alloy coating can be deposited using electroless plating followed by application of a surface coating. Several illustrative methods are described below.

The electrodeposition technique desirably provides the formation of a coating which comprises some or all of the characteristics or features described herein, e.g., can be hydrophobic and/or comprises a large water contact angle. Electrodeposition methods may comprise providing an electrolyte mixture. Possible compositions of this mixture are discussed below. Steps such as cleaning or activating the substrate and placing that in the electrolyte mixture can be performed.

In some embodiments, in a two-electrode electrodeposition process, such as that depicted in
In certain examples and while not wishing to be bound by any particular theory, the electroplating process is based on a nucleation and growth mechanism. Non-homogeneous conditions during the nucleation and growth process can result in the formation of textures on the surface of the growing material layer. When the conditions of the growth are not homogeneous, different locations of the surface encounter different growth rates. Some locations grow faster and form peaks while others grow slower and become valleys. This presence of these different resulting features can provide for a surface texture on the substrate. In electroplating, different parameters such as voltage, bath composition, agitation, and bath temperature can be adjusted to control the level of non-homogeneity in the nucleation and growth process, and therefore, make different surface textures. In some instances, the electroplating conditions can be altered during surface coating formation to promote the formation of the textures surfaces. The effects of the process parameters on the deposit surface texture can be better understood by the following non-limiting explanation on the effects of voltage and bath composition. In some examples, the applied voltage can be controlled or tuned during coating to promote formation of textured surfaces. The effect of the applied voltage can be explained by unstable growth theories such as Mullins-Sekerka instability model (see, for example, Mullins and Sekerka, Journal of Applied Physics, Volume 35, Issue 2 (2004). Based on these theories, diffusional mass transfer favors the growth of the arbitrary protrusions of the surface and enhances the morphological instabilities or texture of the growing surface. By controlling the applied voltage, desired growth rates and effects for the surface textures can be achieved.
In certain configurations, similar to the applied voltage, the concentration of different species of the electrolyte can also affect the level of diffusional mass transfer in the bath and, therefore, can have an effect on the deposited surface textures. In addition to this effect, bath composition can have other interesting effects on the deposit surface texture, which is called the additive effect. The additive effect refers to the effect of a chemical reagent on making non-homogeneous growth conditions and subsequently forming a surface texture. Different chemical reagents can undergo different mechanisms to promote the non-homogeneous growth condition.
In certain examples, the exact attributes and properties of the coatings described herein can vary depending on the particular materials which are present, the coating conditions used, etc. In some examples, the surface features of the textured layer of the coatings may exhibit a hierarchical structure. Hierarchical structure refers to the condition where each surface feature comprises smaller features. The size of surface features in hierarchical structures can desirably be at least two times larger than their constituent features. As a prophetic example, the first feature size might be 10 microns while the second feature size is 1 micron.
In certain instances, one or more of the coating layers may comprise nanoparticles. Illustrative nanoparticles can include, but are not limited to, PTFE particles, silica (SiO2) particles, alumina particles (Al2O3), silicon carbide (SiC), diatomaceous earth (DE), boron nitride (BN), titanium oxide (TiO2), platinum oxide (PtO2), diamond, particles formed from differential etching of spinodally decomposed glass, single wall carbon nanotubes (SWCNTs), mix silicon/titanium oxide particles (TiO2/SiO2, titanium inner core/silicon outer surface), ceramic particles, thermo-chromic metal oxide, multi-wall carbon nanotubes (MWCNTs), any chemically or physically modified versions of the foregoing particles, and any combination thereof.
In certain configurations, in addition to the electrodeposited and surface coatings, the overall coating can comprise other layers as well. Each coating layer can be distinguished from its top and underneath layers by its different composition. Two adjacent layers might have distinct or indistinct interfaces. Two examples of multiple-layer coatings are discussed below. In a first example, the condition wherein one or multiple conformal coating layers are present on top of the electrodeposited layer is described. Conformal layers are defined as the coating layers that approximately follow the surface texture of their underlying layer. The conformal coating layer can comprise one or more of Chromium Nitride (CrN), Diamond Like Carbon (DLC), Titanium Nitride (TiN), Titanium Carbo-nitride (TiCN), Aluminum Titanium Nitride (ALTiN), Aluminum Titanium Chromium Nitride (AlTiCrN), Zirconium Nitride (ZrN), Nickel, gold, PlasmaPlus®, Cerablack™ Chromium, Nickel Fluoride (NiF2), any Nickel Composite, any organic or inorganic-organic material and combinations thereof. Examples of nickel composites suitable for use as the conformal coating include, but are not limited to, composites of nickel with different particles selected from a group consisting of PTFE, silica (SiO2), alumina (Al2O3), silicon carbide (SiC), diamond, diatomaceous earth (DE), boron nitride (BN), titanium oxide (TiO2), single wall carbon nanotubes (SWCNTs), multi-wall carbon nanotubes (MWCNTs), kaoline (Al2O3.2SiO2.2H2O), graphite, other nanoparticles, or any combination thereof. Examples of organic or inorganic-organic materials suitable for use as the conformal coating include, but are not limited to, parylene, organofunctional silanes, fluorinated alkylsilane, fluorinated alkylsiloxane, organofunctional resins, hybrid inorganic organofunctional resins, organofunctional polyhedral oligomeric silsesquioxane (POSS), hybrid inorganic organofunctional POSS resins, silicone polymers, fluorinated oligomeric polysiloxane, organofunctional oligomeric poly siloxane, fluorinated organofunctional silicone copolymers, organofunctional silicone polymers, hybrid inorganic organofunctional silicone polymers, organofunctional silicone copolymers, hybrid inorganic organofunctional silicone copolymers, fluorinated polyhedral oligomeric silsesquioxane (FPOSS), Dynasylan® SIVO, other similar groups, or any combination thereof.
In some instances, two or more different types of organofunctional silanes can be present in any one layer. For example, an organofunctional silanes, or two or more organofunctional silanes, can be co-deposited with one or more of the other materials described herein. As noted herein, organofunctional silanes are a group of compounds that combine the functionality of a reactive organic group with inorganic functionality in a single molecule. This special property allows them to be used as molecular bridges between organic polymers and inorganic materials. The organic moiety of the silane system can be tailored with different functionalities consisting amino, benzylamino, benzyl, chloro, fluorinated alkyl/aryl, disulfido, epoxy, epoxy/melamine, mercapto, methacrylate, tetrasulfido, ureido, vinyl, vinyl-benzyl-amino, and any combination thereof.

In certain examples, processes other than electrodeposition processes can also be used in production of the coatings. The layer adjacent to the substrate can be produced, for example, through a process comprising a combination of the electrodeposition techniques and any other technique selected from the group consisting of annealing and thermal processing, vacuum conditioning, aging, plasma etching, grit blasting, wet etching, ion milling, exposure to electromagnetic radiation such as visible light, UV, and x-ray, other processes, and combinations thereof. In addition, the manufacturing process of the layer adjacent to the substrate can be followed by at least one additional coating process selected from the group consisting of electrodeposition, electroless deposition, surface functionalization, electro-polymerization, spray coating, brush coating, dip coating, electrophoretic deposition, reaction with fluorine gas, plasma deposition, brush plating, chemical vapor deposition, sputtering, physical vapor deposition, passivation through the reaction of fluorine gas, any other coating technique, and any combination thereof.
In certain instances, the coatings described herein can provide heat-resistant characteristics at least up to a certain maximum temperature. This characteristic is observed if a water contact angle of the coating changes less than 20 percent after the coating is subjected to a thermal process at 100° C. or higher for 12 hours or longer. In some examples, the coatings can be heat-resistant up to about 300 degrees Celsius, 350 degrees Celsius or 400 degrees Celsius.
Certain specific examples of coated articles that provide corrosion resistance are described below to illustrate further some of the novel and inventive aspects of the technology described herein. Damage to components can be caused by wear, corrosion, high temperature or by a combination of these three modes. The examples below describe the performance of the coating in exposure to different damaging factors. Almost in all tests, the damaging factor is exaggerated compared to the real environment. Therefore, the tests represent accelerated damaging condition or conditions which are generally much more harsh than those experienced by most substrates in their use environment.
All articles that includes a MaxShield™ coatings in the examples below included a layer comprising nickel and molybdenum. An optional surface coating including a reaction product of a silane system with the underlying coating can be added if desired to further enhance certain properties.
A coated surface of an article (carbon steel) was immersed in an aqueous solution of concentrated hydrochloric acid (32% HCl) for 24 hours. The weight loss of the coating (labeled as MaxShield) after the 24-hour exposure was then used to calculate its corrosion rate.
The rate shown for the coatings in
While the exact anti-corrosive mechanism of the MaxShield™ coating is not yet fully understood, one of the reasons for this superior anti-corrosion performance of the MaxShield™ coating could be its repellency. Third-party testing shows that the coating remains hydrophobic after 24-hour exposure to concentrated hydrochloric acid. In these tests, a Theta Lite Optical Tensiometer (Biolin Scientific, Paramus, N.J.) was used to measure water contact angles of the samples before and after their exposure to concentrated hydrochloric acid. The test was performed on three different samples. Water contact angles of all samples both before and after 24 hours exposure to the concentrated acid was above 90°.
Hydrogen embrittlement or hydrogen-induced cracking is a type of corrosion that can result in catastrophic failure of steel structures. In this process, brittle hydrides are formed into the steel structure due to the introduction and subsequent diffusion of hydrogen into the metal. The formation of these hydrides results in a sudden fracture of the whole structure. One incident of hydrogen embrittlement was catastrophic failure of the threaded seismic anchor rods of California's San Francisco-Oakland Bay Bridge in 2013. Since this mode of corrosion can be catastrophic, the MaxShield™ coating was tested to determine if it induced hydrogen embrittlement. The test was performed on four notched bars covered with our coating by an accredited third-party lab.
Third-party testing shows a Vickers hardness of 660 to 750 for as-plated surface of carbon steel covered with the MaxShield™ coating. The test results also show that if the coating is annealed after plating at 300 deg. C. to 600 deg. C. for 1-6 hours, its microhardness will increase to 852. Table 2 compares the Vickers hardness of the as-plated and heat-treated surfaces covered with our coating with those obtained for surfaces covered with several other hard coatings.
It is worth mentioning that electroless nickel is a wear-resistant coating that is known as one of the replacements for hard chromium coating. As Table 2 shows the microhardness of the as-plated MaxShield™ coating is better than that of the as-plated electroless nickel coating. Moreover, the heat-treated MaxShield™ coating exhibits slightly better Vickers hardness than heat-treated electroless nickel coating. The hardness of the heat-treated MaxShield™ coating is also comparable with that of the hard chromium coating. An important point that should be mentioned in reference to Table 2 is that hardness of hard chromium coating is reduced at high temperatures. As an instance, if hard chromium is heated at 190 C for 23 hours its hardness reduces from 800-1000 to a value between 700-750.
Therefore, regardless of environmental regulations and mandates on eliminating hard chromium coating, this coating does not perform at wear-resistant applications with high operating temperatures. An example of these applications is coating for inside gun barrels or coating on pistons; rotating parts (piston shafts, bearings) of heavy machineries; as turbine-aero engine parts operating at high temperature and wear environments such as valves (opening and shutting wear), pistons, actuators, piston rods, landing gears and drilling equipment (mud motor rotors, pump plungers, valve components, mandrels, torque rings, etc). Replacing hard chromium coating with the MaxShield™ coating for these applications can result in more durability and better performance.
The Standard Taber abrasion test was used to perform accelerated wear testing following ASTM D4060 standard. In this test, the abrader machine shown in
Hydrogen sulfide cracking tests were performed according to NACE TM-0284 on coated surfaces by an accredited third-party lab. During this testing, the coated surfaces were introduced to an acidic environment for 96 hours, during which H2S gas and nitrogen purge gas are introduced. To evaluate the coatings, the coated surfaces are polished metallographically to highlight cracks caused by the H2S gas. Shown in
Salt spray testing was performed to evaluate the MaxShield™ coating. This test is a standard corrosion test, also known as salt fog test. During this test, the coated surface of the article was exposed to 5% sodium chloride mist which simulates marine environment corrosion. Test was done according to ASTM B 117 by an accredited third-party test center. In this test, a hard chrome coating as well as an electroless nickel coating were compared with the MaxShield™ coating after 1000 hours of exposure.
Corrosion ratings were given by the third-party test specialists according to the ASTM D610 Rust Grade. According to this ASTM, a corrosion rate of 0 for electroless nickel after 1000 hours indicates rust formation over 50% of the surface area. A corrosion rate of 4 was obtained for the hard chromium coating after 1000 hours that indicates 3 to 10% of the surface area is corroded.
The salt spray test also shows a corrosion rate of 9 for three of the carbon steel surfaces covered with the MaxShield™ coating. A corrosion rate of 9 indicates rust formation in less than 0.03% of the surface area. The fourth surface covered with our coating did not rust at all, and its corrosion rate ranked 10.
We also scribed one of the surfaces covered with the MaxShield™ coating and tested that in the salt spray chamber. The corrosion rate of 9 was obtained on the areas far from the scribed region. Moreover, creep measurement was performed on this sample, and the rating of 8 was obtained for the scribed region based on ASTM D1654. The image of the scribed coated surface after 1000 hours exposure to the salt spray is shown in
The test on the scribed surface shows that the MaxShield™ coating does not have any problem with accelerated galvanic corrosion if it gets scratched and the underneath steel surface gets exposed at the location of the scratch. Galvanic corrosion is a major issue with some other corrosion resistant coatings. When these coatings get scratched, the underneath steel sacrificially corrodes, and the coating remains intact. Therefore, the coating fails in performing its main duty of protective the steel substrate. The results of the salt spray test on the MaxShield™ scribed coating shows that the MaxShield™ coating can provide a level of self-healing and limit the progress of corrosion from the scratched location. Without the intent to limit this self-healing characteristic to any particular reason, it is believed the MaxShield™ coating provides a protective oxide film at the location of the scratch that can prevent further progress of the corrosion.
Ductility of the MaxShield™ coating was determined by an accredited third-party testing center according to ASTM E8 (Tension Testing of Metallic Materials). In this test, coated T-bone specimens are tensile tested uniaxially until the coating flakes off and the underneath surface can be seen in 50x microscopic images.
The test showed that the MaxShield™ coating can get elongated to above 6% without any flaking or fracturing. The ductility values, greater than 6%, is significantly higher than commercially used hard chrome coatings which is 0.1% and also electroless nickel which is 1-1.5%.
The water contact angle (WCA) of the MaxShield™ surface is always above 90°. However, this angle can be tuned based on the substrate below the coating, the coating composition and by varying parameters of the coating application process. WCA is generally between 110° and 125°. This angle can be compared with the WCA of uncoated steel that is between 60° to 80°.
Three MaxShield™ coated stainless steel surfaces were immersed in an aqueous solution of 20% NaOH for 24 hours with the coating in a vertical position. After the 24 hours exposure, coatings were washed with deionized (DI) water and wiped dry, followed by being subjected to a heat drying program. After the heat drying program, coatings were weighed, and their water contact angle was measured.
The weight loss remained below 1 mg/cm2 and water contact angle remained above 100° after 24 hours exposure to the alkaline environment in this test. The average weight loss and contact angles of the coating are provided in Table 4 below. Moreover, as shown in
Three MaxShield™ coated stainless steel surfaces were immersed in reagent grade acetone for 24 hours with the coating in a vertical position. After 24 hours exposure, coatings were washed with deionized water and wiped dry. Coatings were then subjected to a heat drying program. After the heat drying program, coatings were weighed, and their water contact angle was measured.
Three coated samples exhibited weight loss of less than 1 mg/cm2 and contact angle of more than 90° after 24 hours exposure to acetone. Weight loss and contact angles of the samples are provided in Table 5 below. No damage was observed on the coating after 24 hours exposure to acetone. As a result, the coating can resist organic solvent environments without any corrosion and loss of hydrophobic property.
Three coated stainless steel surfaces were immersed in an aqueous solution of 32% HCl for 24 hours with the coating in a vertical position. After 24 hours exposure, coatings were washed with DI water and wiped dry. Coatings were then subjected to a heat drying program. After the heat drying program, coatings were weighed and their water contact angle was measured. It is worth mentioning that 32% HCl is a concentrated HCl solution. It is a very corrosive environment that will destroy most materials other than such super-alloys as Hastelloy.
The weight loss of all three samples was less than 10 mg/cm2 and their contact angles remained above 90° after 24 hour exposure to the concentrated acidic environment. Table 6 shows the average weight loss per unit area for three samples and their water contact angles before and after the test. The results show the coating resists in this aggressive environment and retains its properties.
Three coated stainless steel surfaces were placed in an oven at 300° C. for 24 hours. Following the exposure, the contact angles were measured.
The water contact angle of all three coatings remained above 90° after the test. Moreover, no significant discoloration and damage was observed.
Pencil hardness testing was conducted per ASTM D 3363 on MaxShield™ coated stainless steel surfaces.
A pencil hardness of more than 9H was obtained for the coated surfaces. It is worth mentioning that 9H is the highest grade of pencil hardness. No scratching or gouging of the coating was observed. Transfer of graphite material from the pencil covered the stroke length.
A cross section of a single surface was analyzed. Examination of several MaxShield™ coated surfaces in cross section showed that coating thickness can be between 25 to 100 micrometers.
In this test, three MaxShield™ coated stainless steel surfaces were exposed to heat at 300° C. for around 25 days. The coated surfaces were taken out of the oven every 2 or 3 days, cooled down to the room temperature, and their mass and water contact angles were measured. The samples were then heated up again to 300° C. This test can be a measure of the performance of the coating in long time exposure to heat and heat cycling.
The MaxShield™ coated stainless steel samples experienced negligible weight loss and their water contact angle remained above 90° in this long-term test. The circles in
Less wear means more reliable moving parts (sliding, rotating, rubbing) in an abrasive environment. Therefore, it can be translated to longer life of equipment and more efficiency. The wear performance of the MaxShield™ coating was tested per ASTM G99 specification.
The test was involved in applying 10 N force through a hard ball made of 440C stainless steel onto the coated sample that rotates 200 revolution per minute. The mechanical metal-to-metal contact causes wear loss on the coating which is controlled by the coefficient of friction and hardness of the coating.
The test results are tabulated for the heat-treated and as-plated coatings and compared to those of industrial coatings (hard chromium and electroless nickel coating) in Table 7. In this table, wear factor indicates wear with a lower value indicating a better performance. The MaxShield™ coating showed superior wear performance against an industrial electroless nickel coating (wear factor of about 86.52). However, the results show that the wear performance of industrial hard chromium coating remains better than the two tested versions of the MaxShield™ coating.
In reviewing the track of the abraded disks after testing, a track is barely seen on the hard chromium coating. On the heat-treated version of the MaxShield™ coating the crack is much smaller than the one on the electroless nickel coating. A narrower track can be interpreted to better wear performance. The ball wears off in the contact with the hard chromium coating because the coating is harder than the ball, and as the image shows there is no material transfer on the ball. In contrast there is a large amount of debris on the ball after its contact with electroless nickel coating. Material transfer from to coating to the ball shows that the coating is not as hard as the ball. Both versions of the disclosed MaxShield™ coatings are in between these extreme cases. There are small amount of materials transfer from the coating to the ball and there is a clear sign of damage on the ball as well.
