Galvanized steel sheet
Abstract:
The present invention provides a galvanized steel sheet including: a steel sheet; and a galvanizing layer provided on a surface of the steel sheet; wherein the galvanizing layer includes an amorphous coating layer having an inorganic oxoacid salt and metallic oxide on a surface layer of the galvanizing layer; the galvanizing layer includes a ζ phase and a δ1 phase; the galvanizing layer includes, by mass, 8 to 13% of Fe; Zn in the metallic oxide exists up to an outermost surface layer of the amorphous layer; and an X-ray diffraction intensity ratio I, which is obtained by dividing an X-ray diffraction intensity of the ζ phase at d=0.126, after removing background intensity, by an X-ray diffraction intensity of the δ1 phase at d=0.126, after removing background intensity, is 0.06 to 0.35.
