摘要： The present invention provides a composite coated zinc-containing plated steel material different from the plated steel materials treated by conventional chromate replacement technologies and superior in all of corrosion resistance, blackening resistance, coating adhesion, and alkali resistance. 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 (VO 2+ )-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%.

摘要： A zinc-plated steel material coated with a composite film, which is excellent in all of corrosion resistance, unsusceptibility to blackening, coating adhesion, and alkali resistance unlike plated steel materials treated by conventional chromate-substitute techniques. The zinc-plated steel material coated with a composite film has a composite coating film formed by applying on the surface of a plated steel material a treating liquid comprising a basic zirconium compound, a vanadyl (VO2+)-containing compound, a phosphoric acid compound, a cobalt compound, an organic acid, and water and having a pH of 7-14 and drying the liquid. It is characterized in that this composite coating film contains 10-45 mass% V, 5-100 mass% P, 0.1-20 mass% Co, and 10-90 mass% the organic acid based on the Zr.
