Abstract
PURPOSE: To provide a zinc-iron alloy-electroplated steel sheet with superior press workability and spot weldability as well as good corrosion resistance and printability by electrolyzing a sheet in an electroplating bath contg. zinc and iron ions to electrodeposit iron and zinc in a specific ratio on the sheet surface.
CONSTITUTION: A steel sheet is electrolyzed in an electroplating bath contg. zinc and iron ions to electrodeposit zinc and 7W80, pref. 10W65% of iron, thus providing a zinc-iron alloy-electroplated steel sheet for spot welding and pressing. For example, the sheet can be manufactured by carrying out electrolysis at a current density of 30 A/dm2 in a short time in a plating bath of pH 1W2 contg. about 250 g/l of FeSO4.7H2O, about 10W100 g/l of ZnSO4.7H2O and an adequate amt. of a pH regulator such as ammonium sulfate.
