ABSTRACT:
A composite zinc-aluminum dispersion plated steel sheet and a method of producing same are disclosed. The plated steel sheet comprises an electrolytical zinc plated layer containing 1.5 to 70% by weight of aluminum dispersed therein. The method comprises adding aluminum powder to an electrolytical zinc plating bath composition, dispersing the aluminum powder into the plating bath to provide a composite zinc-aluminum dispersion plating bath, and electrolytical treating a steel sheet in the composite zinc-aluminum dispersion plating bath while agitating it. The plated steel sheet enhances corrosion resistances and does not show any spangles which impair the appearances after subsequent painting of the plated steel sheet.
