Abstract
A process for the production of copper or a copper base alloy that provides a surface having improved characteristics suitable for the production of a connector or a charging-socket of an electric automobile by having a decreased coefficient of friction on the surface and improved resistance to abrasion. The process comprises coating copper or a copper alloy with Sn, followed by heat treating the resulting Sn-plated copper or copper base in an atmosphere having an oxygen content of no more than 5%, thereby forming on an outermost surface thereof an oxide film and beneath the surface a layer of an intermetallic compound mainly comprising Cu—Sn.
