IPC: C23C28/02
Filed: 1988-11-28
Abstract: PURPOSE:To obtain a plated steel sheet excellent in crater resistance, coating properties, workability and corrosion resistance by pickling the allowed hot dip galvanized steel sheet to dissolve the surface layer at specified amount and thereafter performing specified Zn-Fe flash plating. CONSTITUTION:An alloyed hot dip galvanized steel sheet having a plated layer contg. 5-30wt.% Fe amount is pickled. In this case, the dissolved amount by pickling is regulated to 0.05-1.0g/m<2> by controlling the pickling conditions and thereby the oxidized film on the surface is removed. Thereafter Zn-Fe flash plating is performed on the plated steel sheet. In this case, Fe amount of the flash plating layer is regulated to 60-95% and the build-up amount of flash plating is regulated to 2-10g/m<2>. Thereby the surface of the hot dip galvanized steel sheet is smoothed and Zn-Fe flash plating contg. large amounts of Fe is uniformly stuck on the surface thereof.
