Abstract

PURPOSE:To obtain the titled plated steel sheet having fine luster on the plated surface and superior corrosion resistance without using a special brightener, by electroplating a steel sheet with an acidic zinc-silica plating bath contg. nitrate ions at a specified concn. besides colloidal silica. CONSTITUTION:An unplated steel sheet, a galvanized steel sheet or a zinc alloy plated steel sheet is electroplated with an acidic zinc-silica plating bath prepd. by adding colloidal silica and 3,000-20,000ppm nitrate ions to a basic acidic galvanizing bath. Thus, a plated steel sheet having superior corrosion resistance and fine luster on the plated surface can be obtd. The plated surface is hardly scratched.
