    摘要: The invention concerns a process, not using chlorate or nitrite, for the production of nickel and manganese containing zinc phosphate films on steel, zinc, and/or zinc alloys by spraying, spray-dipping, and/or dipping, using an aqueous solution. An organic oxidizing agent is added, primarily to depolarize the nascent hydrogen produced.

    摘要: Activation of metal surfaces prior to phosphating can be improved by using aqueous dispersions of polymeric titanium(IV) phosphates in which at least 95% by weight of the polymeric particles have a particle diameter of less than 200 nm. This low particle diameter is attained by adding a titanium(IV)-complexing agent before or during an otherwise conventional reaction between a titanium(IV) compound, acid or phosphate, and water. The complexing agent is used in an amount of less than the stoichiometric amount, based on the titanium(IV) content. The best complexing agents are poly(aldehydocarboxylic acids), 1,1-diphosphonic acids, and/or the alkali metal salts of these types of acids.

    摘要: In a process for phosphatizing electrolytically and/or hot-dip galvanized steel strip, the steel strip is briefly treated with acidic phosphatizing solutions which contain, in addition to zinc and phosphate ions, manganese and nickel cations and anions of oxygen-containing acids with an accelerator effect. The weight ratio of nickel cations to nitrate anions is adjusted to between 1:10 and 1:60 and the weight ratio of manganese cations nitrate anions is adjusted to between 1:1 and 1:40.
