摘要： A process for phosphating surfaces of steel, galvanized or alloy-galvanized steel, aluminum, aluminized or alloy-aluminized steel. The process is particularly useful for treating metal surfaces which are to be cathodic electrocoated. The process uses a nickel, cobalt, copper, nitrite and oxo-anion of halogen free phosphating solution containing 0.3 to 2.0 g/l Zn(II), 0.3 to 4 g/l Mn(II), 5 to 40 g/l phosphate ions and at least one of 0.5 to 5 g/l hydroxylamine and 0.2 to 2 g/l m-nitrobenzene sulfonate wherein the ratio by weight of Zn(II) to Mn(II) is not greater than 2.

摘要： A process for post-passivation of a phosphated metal surface, characterized in that the phosphated metal surface is treated with an aqueous post-passivation solution which contains from 50 to 500 mg/l of nickel ions and from 200 to 1500 mg/l of phosphate ions. Rinsing water arising which contains constituents of the post-passivation solution may be processed by nanofiltration or reverse osmosis, the retentate being transferred into the phosphating bath, thereby closing the Ni circuit. The post-passivation solution preferably additionally contains a phosphating accelerator.

摘要： The present invention relates to an aqueous composition and to a method for the anticorrosion conversion treatment of metallic surfaces, particularly metallic materials which are assembled into composite structures, comprising steel or galvanized or alloy-galvanized steel and any combinations of these materials, the composite structure being composed at least in part of aluminum or the alloys thereof. The aqueous composition according to the invention is based on a phosphating solution and contains, in addition to water-soluble compounds of zirconium and titanium, a quantity of free fluoride in a ratio that both permits phosphating of the steel and galvanized and/or alloy-galvanized steel surfaces and determines low pickling rates with regard to the aluminum substrate with simultaneous passivation of the aluminum. The metallic materials, components and composite structures conversion treated in accordance with the underlying invention are used in automotive body construction, in shipbuilding, in construction and for the production of white goods.
