    摘要: The invention provides an aluminum alloy sheet having improved formability, an elongation of at least 30%, a sliding frictional resistance of up to 0.13 and minimized surface pressure dependency of sliding frictional resistance, comprising an aluminum alloy substrate containing at least 4 wt % of Mg and a Fe rich plating layer on a surface thereof in a coating weight of 1 to 50 g/m.sup.2. Also provided is a bake hardenable, surface treated aluminum alloy sheet having improved formability, an elongation of at least 25%, a sliding frictional resistance of up to 0.13 and minimized surface pressure dependency of sliding frictional resistance, comprising a bake hardenable aluminum alloy substrate containing Mg and Si in an amount of at least 0.4 wt % calculated as Mg.sub.2 Si and a Fe rich plating layer on a surface thereof in coating weight of 1 to 50 g/m.sup.2. By forming a zincate layer as an undercoat below the Fe rich plating layer, the plating adhesion is further improved. The preferred Fe rich plating layer is a Fe-Zn alloy plating layer containing 20 to 80 wt % of Zn for corrosion resistance improvement. A Fe-Zn alloy plating layer containing 30 to 40 wt % of Zn meets both formability and corrosion resistance.

    摘要: Provided are an apparatus for continuous electrolytic treatment of a steel sheet that is suitable for producing a surface-treated steel sheet and a method for producing the surface-treated steel sheet using the apparatus for continuous electrolytic treatment of a steel sheet. The apparatus includes N pairs of tabular electrodes having a length L and being arranged to respectively face two surfaces of a steel sheet. Each electrode includes n sections arranged in the longitudinal direction of the electrode and disposed on the surface of the electrode facing the steel sheet surface. Each section is constituted by a conductive portion including an electrode portion having a length T1 and a nonconductive portion made by making an electrode portion having a length T2 nonconductive, where n×N≧10, 0.96≧T2/(T1+T2)≧0.05, and 0.9≧T1/L≧0.1.
