METHOD FOR MANUFACTURING HOT-DIP ZN ALLOY-PLATED STEEL SHEET |
摘要 |
A hot-dip Zn alloy plating layer is formed on a surface of a base steel sheet by immersing the base steel sheet in a hot-dip Zn alloy plating bath containing Al and Mg. An aqueous solution containing one of or two or more of polyatomic ions selected from the group consisting of a polyatomic ion including V5+, a polyatomic ion including Si4+, and a polyatomic ion including Cr6+ is then contacted with a surface of the hot-dip Zn alloy plating layer. The aqueous solution contains the polyatomic ion in a concentration of 0.01 g/L or more in terms of one of or two or more of atoms selected from the group consisting of V, Si, and Cr. |
