| 摘要 |
The present invention relates to a treatment solution for the deposition of a thin organic/inorganic hybrid coating on a zinciferous metal surface, comprising water and (i) a concentration of phosphoric acid (A); (ii) a concentration of dissolved inorganic components (B) containing at least one complex fluoro metallate anion selected from the group of titanium, zirconium, hafnium and/or silicon, preferably hexafluorotitanic acid; (iii) a concentration of dissolved inorganic components (C) consisting of bivalent cations of zinc (C1) and/or manganese (C2); (iv) a concentration of a dissolved inorganic component (D) consisting of oxoanions of molybdenum; (v) a concentration of a water soluble and/or water dispersable polymeric compound (E) which is based on a chelating poly(vinylphenol) compound; (vi) a concentration of a water-soluble and/or water-dispersable polymeric resin (F) being not part of or identical with component (E). |
