PLATED MEMBER, PLATED TERMINAL FOR CONNECTOR, METHOD FOR PRODUCING PLATED MEMBER, AND METHOD FOR PRODUCING PLATED TERMINAL FOR CONNECTOR

Japanese Patent JP2015048483

A

PROBLEM TO BE SOLVED: To provide: a plated member and a plated terminal for a connector, each comprising a silver-tin alloy layer that covers the surface of a basis material and a silver cover layer that covers the surface of the silver-tin alloy layer and each preventing the silver-tin alloy layer from being peeled off; and production methods by which the plated member and the plated terminal for the connector can be produced in a short time.SOLUTION: In a plated member, a silver-tin alloy layer covers the surface of a basis material, a silver cover layer covers the surface of the silver-tin alloy layer, and the silver cover layer is exposed on the outermost surface. The silver-tin alloy layer exhibits, over the whole thickness region, an area fraction of voids of 30% or less in any plane parallel to the surface of the basis material. A method for producing the plated member comprises the steps of: laminating tin plating layers and silver plating layers formed using a selenium-containing plating solution, alternately on the surface of a basis material to form a laminated product in which the outermost layer is a silver plating layer; and then heating the laminated product.
