GALVANIZED STEEL SHEET EXCELLENT COATING ADHESION AND CORROSION RESISTANCE PROPERTIES AND METHOD FOR MANUFACTURING THEREOF

摘要

One aspect of the present invention is to provide a galvanized steel sheet having excellent plating adhesion as well as improved frictional properties and excellent corrosion resistance by plating with a certain level of Fe elution. The galvanized steel sheet includes: a plated steel sheet; a galvanized layer that includes 5.1-35.0 wt% of Al, 4.0-25.0 wt% of Mg, and the balance An and other inevitable impurities; and an Al-Fe inhibition layer having a thickness of 0.01-15 μm on the interface between the plated steel sheet and the galvanized layer.
