Abstract

A composite plating film is prepared from a composite plating solution containing a metal matrix and insoluble particles 4 dispersed therein or deposited therewith. The composite plating film has a non-uniform concentration of insoluble particles along a direction of the thickness of the composite film. The non-uniform concentration is achieved by changing the discharge rate of composite plating solution during deposition of the film on the base material.
