The composite coated zinc-containing plated steel material of the present invention is characterized by having a composite coating formed by coating and drying on the surface of a plated steel material a treatment solution containing a basic zirconium compound, vanadyl (VO2+)-containing compound, phosphoric acid compound, cobalt compound, organic acid, and water and having a pH7 to 14, the composite coating containing, with respect to the Zr element as 100 mass %, V in an amount of 10 to 45 mass %, P in 5 to 100 mass %, Co in 0.1 to 20 mass %, and an organic acid in 10 to 90 mass %.

Abstract: Exemplary embodiments of the present invention can provide a galvanization method for hot-rolled steel sheet, cold-rolled steel sheet, or plating sheet of various compositions, which can avoid nonplating defects by using an Ni preplating procedure. For example, an exemplary galvanization method can be provided for pickled hot-rolled steel sheet or annealed cold-rolled steel sheet which is free from non-plating defects which includes cleaning the surface of the plating sheet, preplating it with Ni, rapidly heating the sheet in a nonoxidizing or reducing atmosphere to a sheet temperature of about 430 to 500° C. at a heating a rate of about 20° C./sec or more, and then hot dip plating the sheet in a galvanization bath. The exemplary amount of Ni preplating can be determined based on the plate type and amount of Si in the sheet steel to produce a hot dip galvanization that is free from non-plating defects.

Abstract: Exemplary embodiments of the present invention can provide a hot dip galvannealed steel sheet which has excellent corrosion resistance, workability, coatability and appearance. The exemplary galvannealed sheet can include an ultra-low carbon steel sheet having a plating layer which includes about 8 to 13% Fe, about 0.05 to 1.0% Ni, about 0.15 to 1.5% Al, and a balance of Zn and unavoidable impurities. An exemplary method for producing a hot dip galvannealed steel sheet is also provided which can include cleaning an annealed ultra-low carbon steel sheet, preplating it with Ni, rapidly heating the sheet in a nonoxidizing or reducing atmosphere, plating the sheet in a galvanization bath containing Al, wiping it, then rapidly reheating it and either cooling the sheet without any soaking time or soaking and holding it for less than 15 seconds and then cooling it.

Abstract: The present invention provides a metal material given a chrome-free surface treatment satisfying all of the requirements of corrosion resistance, heat resistance, fingermark resistance, conductivity, coatability, and blackening resistance at the time of working, which was difficult to achieve with conventional chromate-free technology. The chromate-free surface treated metal material of the present invention is comprised of a metal material on the surface of which is coated and dried an aqueous metal surface treatment agent comprising an organic silicon compound (W), obtained by blending a silane coupling agent (A) containing one amino group in its molecule and a silane coupling agent (B) containing one glycidyl group in its molecule in a solid weight ratio [(A)/(B)] of 0.5 to 1.7, at least one type of fluorocompound (X) selected from fluorotitanic acid or fluorozirconic acid, phosphoric acid (Y), and a vanadium compound (Z) so as to form a composite coating containing the different ingredients.

Abstract: The present invention aims at provision of an organic composite galvanized steel sheet having its characteristics such as corrosion resistance and workability improved. Thus, the present invention provides an organic composite galvanized steel sheet that is formed by sequentially depositing on a surface of a steel sheet a galvanization layer, a zinc phosphate layer containing Mg, and an organic layer, and is characterized in that a value of Mg/P (weight ratio) in the zinc phosphate layer is 0.15 or larger and an amount of Mg contained in the zinc phosphate layer is 20 mg/m2 or more. Preferably, the zinc phosphate layer contains one or two or more of Ni, Mn, Co, Fe, Cu, Al, and Ca. In one preferred embodiment, the organic layer is formed as a composite layer containing an organic resin and one or two kinds or more of powder or colloid selected from SiO2, Al2O3, MgO, Fe2O3, Fe3O4, ZrO2, TiO2, and SnO2.
