ABSTRACT:
A composite copper alloy having a modified surface is provided. An element or combination of elements both soluble in copper and reactive with nitrogen are cast with copper or a copper alloy forming a solid state solution. The alloy is reacted with a nitride former to modify the surface. A continuous surface film is formed by heating in a nitrogen containing gas. A dispersion of nitride precipitate in a copper matrix is formed by implanting nitrogen ions.
