Abstract

PURPOSE:To improve the corrosion resistance and spot weldability of a plated steel sheet by forming an Al-Zn plating layer having a prescribed Al content and a prescribed thickness on the surface of a steel sheet and by further forming a prescribed Fe-Al-Zn plating layer on the Al-Zn plating layer. CONSTITUTION:Zn and Al are vapor-deposited on a steel sheet in a vacuum atmosphere under <=10<-1>Torr atm to form an Al-Zn alloy plating layer having 4-80wt.% Al content and >=2mum thickness. Zn, Al, Fe are then vapor-deposited on the Al-Zn alloy plating layer in a vacuum atmosphere under <=10<-1>Torr atm to form an Fe-Al-Zn ally plating layer having 40-90wt.% Fe content, 0.5-4wt.% Al content and >=0.03mum thickness.
