Abstract

PURPOSE:To obtain a composite electroplated steel sheet excellent in corrosion resistance, by dispersing the fine grains of chromate into a Zn-Ni alloy plating solution containing Cr, Co, Al, Sn, Pb, Mo, Sb, etc., and applying it to a steel sheet. CONSTITUTION:A coating layer of Zn-Ni alloy plating containing one or more elements among Cr, Co, Al, Sn, Pb, Mo, and Sb is applied to one side or both sides of a steel sheet. At the time of this Zn-Ni alloy plating, the fine grains of chromate and further, if necessary, the fine grains of one or more kinds among TiO2, ZrO2, Cr2O3, SiO2, and Al2O3 are dispersed. As the above chromate, PbCrO4, BaCrO4, etc., having limited solubility in the plating bath are suitably used, and preferred content of the above in the plating layer is about 0.01-30wt.% based on the coating weight. By this method, a Zn-Ni composite electroplating layer in which the fine grains of chromate, etc., are uniformly dispersed can be obtained, and the corrosion resistance of the steel sheet can be improved.
