Method for production of surface treated steel sheet, surface treated steel sheet, and surface treated steel sheet coated with resin comprising surface treated steel sheet and organic resin coating the steel sheet
Method for production of surface treated steel sheet, surface treated steel sheet, and surface treated steel sheet coated with resin comprising surface treated steel sheet and organic resin coating the steel sheet
A method for producing a surface treated steel sheet which comprises subjecting a steel sheet to a dipping treatment or an electrolysis treatment in an aqueous solution containing one or more of oxysulfates of Mo, Ti, V and Zr, a P compound and a Zn compound, or, in an aqueous solution further containing a significant amount of one or more of sulfates of Mg and Al and/or a phosphonate in addition to the above; a surface treated steel sheet; and a surface treated steel sheet coated with a resin comprising a surface treated steel sheet and a resin coating the steel sheet which is produced by coating the surface treated steel sheet produced by the above method with an organic resin. The surface treated steel sheet has sufficient resistance to corrosion and sufficient adhesiveness with a resin to replace a surface treated steel sheet which has been subjected to a chromate treatment.
