摘要： 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.

摘要： A counter flow device for a plating apparatus including a rotary drum with its substantially half part immersed in a plating solution in a plating bath, about which a metallic strip to be plated passes in synchronism with rotation of said rotary drum and anodes spaced apart by radial gaps from the strip for causing electric current to flow between the strip and the anodes. According to the invention the counter flow device comprises a bottom nozzle arranged at a bottom of the bath and directing in a direction substantially opposite to an entering direction of the strip thereat and a top nozzle having a nozzle opening whose tip end is immersed in the proximity of a surface of the plating solution at a location where the strip leaves the plating solution, thereby ensuring uniform counter flows over entire gaps between the metallic strip and anodes to remarkably increase critical current density in plating and advantageously realize uniform plating.

摘要： One-side zinc hot dipped steel sheets are produced by coating one surface of a steel sheet with an aqueous slurry of an anti-plating agent based on MgO, alkali metal silicates, boric acid, MOH (M is an alkali metal) and the like and containing such additives as TiO.sub.2 and Al.sub.2 O.sub.3, heating the coated sheet for drying and baking, immersing the steel sheet with an anti-plating film in a molten zinc bath to zinc plate the other surface of the sheet, wetting the anti-plating film, and bending the steel sheet to cause the anti-plating film to peel off, thereby removing the anti-plating film from the steel sheet. This invention carries out the coating and baking of the anti-plating agent such that it is baked to a film having a thickness of 20 to 60 microns at a temperature of 750.degree. C. to about 930.degree. C.
