Claims
- 1. A component assembly for use in living tissue comprising:a ceramic part; a metal part; and a pure nickel interlayer for bonding said ceramic part to said metal part.
- 2. The component assembly of claim 1 whereinsaid ceramic part is selected from the group consisting of alumina, titania, zirconia, stabilized-zirconia, partially-stabilized zirconia, tetragonal zirconia, magnesia-stabilized zirconia, ceria-stabilized zirconia, yttria-stabilized zirconia, calcia-stabilized zirconia, and yttria-stabilized zirconia.
- 3. The component assembly of claim 1 whereinsaid metal part is selected from the group consisting of titanium and titanium alloys.
- 4. The component assembly of claim 1 whereinsaid interlayer material reacts with and forms a eutectic bond between said metal part and said ceramic part.
- 5. The component assembly of claim 1 wherein:said pure interlayer having a thickness of approximately 0.001 inches or less; and said component assembly is heated to a temperature that is less than the melting point of said metal part or of said pure nickel interlayer, but that is greater than the eutectic melting point, thereby forming a bond.
- 6. The component assembly of claim 1 whereinsaid pure interlayer material is a thin coating of essentially pure nickel that is applied to the surfaces that are to be bonded of either said metal part or said ceramic part, by a chemical process selected from the group consisting of electroless plating and electroplating.
- 7. The component assembly of claim 1 whereinsaid pure interlayer material is a thin coating of essentially pure nickel that is applied to the surfaces that are to be bonded of either said metal part or said ceramic part, by a thermal process selected from the group consisting of sputtering, evaporating, and ion beam enhanced deposition.
- 8. The component assembly of claim 1 whereinsaid essentially pure interlayer material is a thin coating of essentially pure nickel that is applied to the surfaces that are to be bonded of either said metal part or said ceramic part, selected from the group consisting of metallic beads and metallic powder.
