    • The invention relates to an at least two-stage method for corrosion protection treatment of metal surfaces, wherein, in a first step (i), an organic coating comprising an aqueous phase (A) is applied to the metal surface and, in a following step (ii), the organic coating applied to the metal surface contacted with an acidic, aqueous composition (B) comprising at least one or more water-soluble compounds containing at least one atom selected from the elements Zr, Ti, Si, Hf, V and/or Ce and one or more water-soluble compounds that release copper ions. The invention further comprises a metal component that is at least partially made of steel, iron, zinc and/or aluminum and the alloys thereof and has been treated by the method according to the invention, and to the use thereof in automobile construction and in the construction industry and for producing household appliances and electronics housings.
    • 本发明涉及一种用于金属表面的防腐处理的至少两级方法,其中在第一步骤(i)中,将包含水相(A)的有机涂层施加到金属表面上,并且在下列步骤 步骤(ii)中,施加到与包含至少一种或多种含有至少一种选自元素Zr,Ti,Si,Hf等原子的原子的水溶性化合物的酸性含水组合物(B)接触的金属表面上的有机涂层, V和/或Ce和一种或多种释放铜离子的水溶性化合物。 本发明还包括至少部分地由钢,铁,锌和/或铝制成的金属组分及其合金,并且已经通过根据本发明的方法进行了处理,以及在汽车结构和 建筑业和家用电器和电子外壳的生产。
