Title:
CHEMICAL CONVERSION TREATED STEEL PLATE, AND METHOD FOR PRODUCING CHEMICAL CONVERSION TREATED STEEL PLATE
Document Type and Number:
WIPO Patent Application WO/2017/163298
Kind Code:
A1
Abstract:
This chemical conversion treated steel plate comprises: a steel plate; a plating layer that contains Ni and is formed on at least one surface of the steel plate; and a chemical conversion coating film layer that is formed on the plating layer and contains a Zr compound in the amount of 1.0-150 mg/m2 in terms of metal Zr content, a phosphate compound in the amount of 1.0-100 mg/m2 in terms of P content, and an Al compound in the amount of 0.10-30.0 mg/m2 in terms of metal Al content. The plating layer is an Ni plating layer that contains Ni in the amount of 5.0-3,000 mg/m2 in terms of metal Ni content, or is a composite plating layer that contains Ni in the amount of 2.0-200 mg/m2 in terms of metal Ni content and Sn in the amount of 0.10-10.0 g/m2 in terms of metal Sn content, and is obtained by forming island-shaped Sn plating layers on an Fe-Ni-Sn alloy layer.
