| description | The invention relates to an aqueous treatment solution for producing conversion coatings on metal surfaces, particularly on zinc or zinc alloy surfaces, said solution containing: Cr(III) ions at an amount of 0.1 g/l to 8.0 g/l, zirconium and/or titanium ions at an amount of 0.1 g/l to 15 g/l, organosilane-modified silicon oxide nanoparticles at an amount of between 0.1 g/l to 50 g/l, and fluorideat an amount of 0.1 g/l to 10 g/l. The claimed treatment solution allows metal materials to obtain a high level of corrosion protection, with the decorative and functional properties of the surfaces simultaneously being achieved or improved. It is also possible to avoid known problems when using heavy metal ions, particularly cobalt and chromium(VI) ions.
本发明涉及种用于在金属表面上、尤其是在锌表面或锌合金表面上产生转化涂层的含水处理液，其中，所述处理液含有：含量为0.1g/l至8.0g/l的三价铬离子；含量为0.1g/l至15g/l的锆离子和/或钛离子；含量为0.1g/l至50g/l的有机硅烷改性的二氧化硅纳米粒子；含量为0.1g/l至15g/l的氟离子。借助根据本发明的处理液，可以提供具有高度防腐蚀性的金属材料，同时可以保持或改善表面的装饰性和功能性特征。此外，当使用重金属离子、尤其是钴离子和六价铬离子时，能够避免已知的问题。 |
