Provided are a Zn—Mg electroplated metal sheet excellent in corrosion resistance, formability and productivity, and a fabrication process therefor. The Zn—Mg electroplated metal sheet comprises a Zn—Mg electroplated layer including Mg and Zn, the Zn being a main component, formed on at least one surface of a metal substrate material. The Zn—Mg electroplated layer shows more excellent corrosion resistance by including a C component therein. The Zn—Mg electroplated metal sheet can be fabricated by performing electroplating with an acidic aqueous solution including metal salts of Zn and Mg, and in addition, a surface active agent.

摘要:
Disclosed is a surface-treated metal material which includes a metallic base including a steel or aluminum material; and an anti-corrosive layer present covering at least one surface of the metallic base. The anti-corrosive layer contains 0.001 to 1 g/m2 of one or more substances selected from the group consisting of benzoic acid salts, glutamic acid salts, anisidines, glycine, and quinolinols. The benzoic acid salts and/or glutamic acid salts are preferably chosen from potassium salt, sodium salt and ammonium salt. Also disclosed is a joined article of dissimilar materials including the surface-treated metal material as at least one of the materials. The surface-treated metal material includes, as the base metal, a steel or aluminum material and is thereby effectively and inexpensively protected from galvanic corrosion without performing electrical insulation or complete atmospheric isolation.
