摘要：
A composite plated metal material having a composite coating layer with excellent adhesion and mechanical properties is produced by (1) displace deposition-plating a metal I base material with a metal II having a nobler oxidation-eduction potential than that of metal I and (2) dope-modifying the resultant metal II coating layer with a metal III-containing deposit in which metal III is different from metal II and exhibits a nobler oxidation-reduction potential than that of metal I, by using a displace deposition-plating aqueous solution containing metal III-containing compound ions.
