    摘要: The coated steel sheet includes a zinc phosphate coating containing Mg on a surface of a galvanized steel sheet, and an orthophosphoric acid ester-containing coating on a surface of the zinc phosphate coating. The coated steel sheet has no coating fall-off even during a chemical conversion treatment step of an automobile producing line and has excellent perforative corrosion resistance either with no-painting or after electrodeposition painting, chemical conversion treatability and press formability.

    摘要: A galvanized steel sheet includes a galvanized coating layer having a coating weight of from about 20 to about 60 g/m2 formed on at least one surface of the steel sheet, and a zinc phosphate coating layer having a coating weight of from about 0.5 to about 3.0 g/m2 formed on the galvanized coating layer. The zinc phosphate coating layer contains from about 0.5 to about 10.0 percent by weight of magnesium, from about 0.1 to about 2.0 percent by weight of nickel, and from about 0.5 to about 8.0 percent by weight of manganese. However, the manganese content and the nickel content satisfy the following relationship: [Ni]×7.6−10.9≦[Mn]≦[Ni]×11.4 wherein [Mn] represents the manganese content, in percent by weight, and [Ni] represents the nickel content, in percent by weight. This steel sheet exhibits superior perforative corrosion resistance. The steel sheet also exhibits superior press workability by further controlling the magnesium, nickel, and manganese contents.

    摘要: The invention provides a material coated with an organic film which exhibits excellent corrosion resistance and lacquer adhesion. The invention includes an electroconductive substrate coated with an electrolytically polymerized coating film containing chromium. Particularly, a zinc-type plated steel sheet coated with an electrolytically polymerized coating film containing chromium in accordance with the invention is well suited for application in vehicle bodies. The invention further provides a method of making a material coated with an organic film which involves forming organic coating material containing chromium on an electroconductive substrate acting as an electrode by electrolytically polymerizing an organic monomer in an electrolyte solution containing chromium. The method provides a monolithic composite structure comprising chromium compounds and an organic coating film, and avoid the problems associated with passivation after chromium plating of steel. The method of the invention can also reduce processing by two-thirds in relation to conventional methods.
