摘要:
In accordance with the invention, a metal substrate is coated with a multilayer surface finish comprising, in succession, an amorphous metal underlayer, a corrosion-resistent metal middle layer and one or more outer layers of precious metal. In an exemplary embodiment the metal substrate comprises copper alloy, the amorphous metal underlayer is Ni—P, the middle layer is nickel and the outer layer is palladium. The resulting structure is particularly useful as an electrical connector.
