METHOD FOR TREATING METAL SURFACE, SILVER-COATED COPPER TREATED BY SAID METHOD, AND COMPOSITE METAL BODY

摘要

Provided is a method for treating a metal surface, in which a metallic copper or copper alloy surface is surface-treated by interposing metallic silver and is compounded, in order to cause, at a relatively low temperature, fusion-induced bonding between such metallic copper (alloy) surfaces. An amine complex of an alkylamine and a silver compound capable of generating metallic silver when decomposed by heat is heated, in the presence of an alkylamine, on a metal surface containing metallic copper or a copper alloy, such that silver is deposited on the metal surface.
