Abstract
A unitary article that is solid at a temperature in excess of about 1100.ree. C. which includes a diamond, a metal, and a brazing material brazing the diamond and the metal. The brazing material includes a metal carbide adhering to the diamond and a platinum family metal or nickel adhering to the metal. The platinum family metal has dissolved therein carbide forming metal and contains particles of metal carbide. The article is made by depositing a platinum family metal or nickel on a metal melting above the melting point of the platinum family metal or nickel, depositing a carbide forming metal which is soluble in molten platinum family metal or nickel, heating the assembly until platinum family metal or nickel is in a molten state, and cooling the molten platinum family metal or nickel to a solid state. In another embodiment, the article of this invention is made by depositing an alloy of nickel and chromium on a metal melting above the melting point of the alloy, depositing a diamond on the alloy, heating to melt the alloy, and cooling the alloy to a solid state.
