| titleOfInvention | Method for producing surface-treated steel sheet and surface-treated steel sheet |
| abstract | The present invention provides a method for producing an environment-adaptive surface-treated steel sheet that does not contain hexavalent chromium harmful to humans and the environment, and has both corrosion resistance and blackening resistance. In forming a film for the purpose of improving corrosion resistance on the surface of a galvanized steel sheet, one or more vanadium compounds having a tetravalent valence and nitric acid or nitrate, or further Y The zinc-based plated steel sheet is subjected to cathodic electrolytic treatment with a treatment liquid containing a metal compound containing a metal selected from La. By performing such electrolytic treatment, the surface of the zinc-based plating film is oxidized and inactivated, and a barrier film mainly composed of a vanadium compound is formed on the steel sheet surface, thereby improving both corrosion resistance and blackening resistance. . [Selection figure] None |
