SURFACE-TREATED STEEL SHEET PROVIDED WITH ANTIRUST COATING FILM AND METHOD FOR PRODUCING SAME |
摘要 |
A surface-treated steel sheet having a Co layer, wherein oxidation of the surface is prevented without deteriorating characteristics such as electrical conductivity. A surface-treated steel sheet which is provided with a Co layer on the surface is immersed in an antirust agent, which contains a fatty acid amine and uses water as a solvent, and then dried, thereby forming an antirust coating film on the surface of the surface-treated steel sheet. The antirust coating film containing the fatty acid amine has a thickness of 10-500 Å (in terms of SiO2) as determined by XPS depth analysis. Preferably, the fatty acid amine is benzenemethanamine or trimethylamine, and more preferably, the fatty acid amine additionally contains benzotriazole. |
