Abstract

PURPOSE:To improve the corrosion resistance of a Zn-Cr electroplated steel sheet after working by forming a chromate film and a resin layer on the surface of the Zr-Cr plating layer contg. a prescribed percentage of Cr. CONSTITUTION:A Zn-Cr plating layer contg. 5-40% Cr is formed on the surface of a steel sheet. A chromate film is formed on the surface of the plating layer and a resin layer is further formed on the surface of the chromate film. When the resulting resin coated Zn-Cr electroplated steel sheet is worked by pressing or other method, the protective film deposits even in cracks in the worked product, so the steel sheet maintains its corrosion resistance even after working.
