Patent Application

In many manufacturing processes, materials must be cut, formed, or drilled and their surfaces protected with wear-resistant coatings. Diamond has traditionally been the material of choice for these applications, due to its superior mechanical properties, e.g. hardness>70 GPa. However, diamond is rare in nature and difficult to synthesize artificially due to the need for a combination of high temperature and high pressure conditions. Industrial applications of diamond are thus generally limited by cost. Moreover, diamond is not a good option for high-speed cutting of ferrous alloys due to its graphitization on the material's surface and formation of brittle carbides, which leads to poor cutting performance.

The novel features of the disclosure are set forth with particularity in the appended claims. A better understanding of the features and advantages of the present disclosure will be obtained by reference to the following detailed description that sets forth illustrative embodiments, in which the principles of the disclosure are utilized, and the accompanying drawings of which:
Wear and tear are part of the normal use of tools and machines. There are different types of wear mechanisms, including, for example, abrasion wear, adhesion wear or attrition wear, diffusion wear, fatigue wear, edge chipping (or premature wear) and oxidation wear (or corrosive wear). Abrasion wear occurs when the hard particle on debris such as chips passes over or abrades the surface of a cutting tool. Adhesion wear or attrition wear occurs when debris remove microscopic fragments from a tool. Diffusion wear occurs when atoms in a crystal lattice move from a region of high concentration to a region of low concentration and the move weakens the surface structure of a tool. Fatigue wear occurs at a microscopic level when two surfaces slide in contact with each other under high pressure, generating surface cracks. Edge chipping or premature wear occurs as small breaking away of materials from the surface of a tool. Oxidation wear or corrosive wear occurs as a result of a chemical reaction between the surface of a tool and oxygen.
In some embodiments, described herein include composite matrix materials that, when applied to a tool or abrasive material, reduce the rate of oxidation wear of the tool or abrasive material, or inhibits oxidation wear of the tool or abrasive material. In some instances, also described herein include methods of manufacturing of the composite matrix, and tools and abrasive materials for use with the composite matrix.

Mixed solutions of W1-xMxXy were synthesized in 99+% purity (SuperMetalix, Inc., USA) using powders of high-purity: boron, berilium and silicon in 99+% purity from Strem Chemicals, U.S.A.; tungsten in 99.99% purity from JMC Puratronic, U.S.A.; titanium, vanadium, chromium, manganese, iron, cobalt, nickel, copper, zinc, zirconium, niobium, molybdenum, ruthenium, hafnium, tantalum, rhenium, osmium, iridium, lithium, yttrium and aluminum in 99+% purity from either Strem Chemicals, U.S.A., Sigma-Aldrich, U.S.A. or JMC Puratronic, U.S.A. Starting materials were mixed and pressed into a 350 mg pellet by means of a hydraulic (Carver) press under 10,000 lbs of force. The pellets were then placed in an arc melting furnace and an AC current of >70 Amps was applied under high-purity argon at ambient pressure.
Tungsten carbide solutions of over 99+% purity were purchased from Fritsch GmbH, Germany. Binder alloys, such as the Co/Ni/Fe alloy used in compound 7 of Table 1 below, were synthesized by Fritsch GmbH with the addition of no more that 2% paraffin wax. The paraffin wax was added to a mixture of the metals as a solution in heptane, and the entire mixture was milled in a planetary ball mill at low speed. The powder was then loaded into a graphite die and prepared for sintering in a spark plasma sinterer (SPS) (Thermal Technologies, USA). The composite was heated at −50° C./min to 1150° C. and held for 3 minutes, then allowed to cool. The composite was pressed and held at 50 MPa for the duration of the synthesis.
The hardness of each sample was determined using a MicroMet 2103 Vickers microhardness tester (Buehler Ltd, U.S.A.). Fifteen indents of the following force loading were made in random areas of the sample: 0.49, 0.98, 1.96, 2.94 and 4.9 N (low to high, respectively). The length of the diagonals were measured using a high resolution optical microscope (Zeiss Axiotech 100HD, Carl Zeiss Vision GmbH, Germany) with 500× magnification, and Vickers hardness was calculated using Equation 1:
where F is the loading force applied in Newton (N) and a is the average of the length of the two diagonals of each indent in micrometers.
Fracture Toughness was determined using the Palmqvist method utilizing a Vickers microindentor with measurements of the crack length to determine the K1C of the material, such as seen in ASTM C1421-18, ASTM STP36630S, and ASTM STP36628S. The crack length of the indentation must fall within the Palmqvist regime to qualify for this determination methodology for this composite material.
Transverse Rupture Strength is determined using a 3-point bend test, as described in B406-96(2015). This methodology is analogous to ISO 3327.
Table 1 shows the compositions of illustrative composite matrix material.
The following protocols can be applied to each of the composite matrices listed above.
The tungsten-based metal composition, tungsten carbide, and binding metal or alloy (T) are mixed until a uniform mixture is achieved. Mixing is performed via tumbling or low-speed milling. Prior to mixing, a solution of paraffin wax or polyethylene glycol is optionally added in no more that 2% by mass. The solvent is an organic solvent of low to moderate polarity, preferably isopropanol or heptane. The mixture is compacted to generate a pellet. If sintering via cold-press, the pellet is pressed into a green body for vacuum and/or isostatic pressing. If sintering with heat, the pellet is placed in a die of a desired geometry for hot-pressing, plasma spark sintering, electric current assisted (arc) sintering, or microwave sintering.
The tungsten-based metal composition, tungsten carbide, and Co/Ni/Fe were mixed using an agate mortar and pestle until a uniform mixture is achieved. The powder mixture was then subjected to pressure of up to 32,000 psi to generate a pellet. The pellet was subjected to a sintering step to generate the composite matrix. During sintering, the temperature was raised at a rate of about 45° C./min to 2000° C. and held constant for about 3 minutes. Then, the temperature was lowered within 5 minutes to below 1000° C. The pellet was then allowed to cool. The composite matrix was characterized with measurements of Vickers hardness (HV30) and fracture toughness. Vickers hardness measurements of composite matrix 7 yielded values ranging between 13.7-15.7 GPa under a force of 294 N (HV30). Fracture toughness measurements yielded a value of 14 MPa m1/2.
