    摘要： Described herein is a method for substantially nickel-free phosphating of a metallic surface, wherein a metallic surface, optionally after cleaning and/or activation, is first treated with an acidic aqueous phosphating composition that includes zinc ions, manganese ions, and phosphate ions, and is optionally rinsed and/or dried, and is thereafter treated with an aqueous after-rinse composition that includes at least one kind of metal ion selected from the group consisting of the ions of molybdenum, copper, silver, gold, palladium, tin, antimony, titanium, zirconium, and hafnium and/or at least one polymer selected from the group consisting of the polymer classes of the polyamines, polyethyleneamines, polyanilines, polyimines, polyethyleneimines, polythiophenes, and polypryroles and also mixtures and copolymers thereof, with both the phosphating composition and the after-rinse composition being substantially nickel-free.

    摘要： A surface treatment liquid contains a resin emulsion that contains a cationic urethane resin emulsion and/or a nonionic acrylic resin emulsion, a tetraalkoxysilane, at least one silane coupling agent (c) that contains at least one reactive functional group selected from active hydrogen-containing amino group, an epoxy group, a mercapto group, and a methacryloxy group, a chelating agent (d), a vanadic acid compound (e), a titanium compound (f), and water in a specific ratio. The surface treatment liquid has a pH of 3 to 6. The surface treatment liquid is applied to a surface of a zinc-based metal coated steel sheet and dried by heating to form a first layer. Next, a surface treatment liquid containing an organic resin is applied to a surface of the first layer and dried by heating to form a second layer.

    摘要： A process for forming a coating on a metal substrate includes contacting the substrate with a molybdate solution having a pH of between 3.5 and 5 inclusive containing an acid with the proviso that the acid is not nitric acid. The substrate is contacted with the solution at a temperature between 30 and 75 degrees Celsius and results in a yellow coating that is kinetically stable from 20 seconds to 300 seconds before the coating darkens to a final black coloration. Water washing of the yellow coating precludes further color development. The resulting yellow coating is amenable to overlayering with a seal coat.

    摘要翻译： 用于在金属基材上形成涂层的方法包括使基材与pH为3.5-5（含酸）的钼酸盐溶液接触，该酸性溶液含有酸，条件是酸不是硝酸。 在30至75摄氏度之间的温度下将底物与溶液接触，导致在20秒至300秒之间动力学稳定的黄色涂层，然后涂层变暗至最后的黑色着色。 水洗黄色涂层排除了进一步的颜色发展。 所得到的黄色涂层适于用密封涂层重叠。
