Abstract

PURPOSE: To provide a title alloy coated steel plate without requiring a gloss imparting agent by a method wherein electroplating is applied to a steel plate under a specific condition by using an acidic zinc plating bath containing Co and Ni ion at a specific ratio.
CONSTITUTION: By using an acidic zinc plating bath having a composition of which a total amount of Zn2+, CO2+ and Ni2+ is above 25g/l, (Co2++Ni2+)/Zn2+ is 1W3 and Ni2+/Co2+ is 0.5W1.6, electroplating is applied to a steel plate at current density of 20W70A/dm2 to obtain a corrosion resistant steel plate coated by a Zn-Co-Ni three component alloy and the surface gloss degree and paintability are remarkably enhanced.
