Title:
SN ALLOY-PLATED STEEL SHEET
Document Type and Number:
WIPO Patent Application WO/2017/204266
Kind Code:
A1
Abstract:
This Sn alloy-plated steel sheet comprises: a steel sheet; a composite alloy layer that is formed on at least one surface of the steel sheet and that comprises an Fe-Ni-Sn alloy layer and an island-shaped Sn layer positioned on the Fe-Ni-Sn alloy layer; and a coating layer that is formed on the surface of the composite plating layer and that contains a zirconium oxide and a tin oxide. The composite plating layer contains a predetermined amount of Ni and a predetermined amount of Sn. The content of the zirconium oxide within the coating layer is 0.2-50 mg/m2 in terms of the amount of metal Zr. The peak position of the binding energy of Sn3d5/2 according to X-ray photoelectron spectroscopy of the tin oxide within the coating layer is greater than the peak position of the binding energy of the metal Sn by 1.6 eV or more.
