Abstract
A composite electroplated steel sheet comprises Zn being a matrix metal of a plating layer; and codeposited particles of a plating layer of at least one selected from the group consisting of Mg.sub.2 Si.sub.3 O.sub.8, CaSiO.sub.3 and BaTiO.sub.3. A composite electroplated steel sheet comprises Zn alloy containing at least one selected from the group consisting of Fe, Co, Ni, Mn, Cr and Ti being a matrix metal of a plating layer; and codeposited particles of a plating layer comprising at least one selected from the group consisting of Mg.sub.2 Si.sub.3 O.sub.8, CaSiO.sub.3 and BaTiO.sub.3. The codeposited particles are contained within the range of from 0.1 to 5.0 wt.% in a plating layer.
