Beschreibung
Zusammenfassung:	The present invention relates to a method for the substantially nickel-free phosphating of a metal surface, in which a metal surface is treated with the following compositions one after the other: i)with an alkaline, aqueous cleaning agent composition, which contains at least a water-soluble silicate, and ii) with an acidic, aqueous, substantially nickel-free phosphating composition, which comprises zinc ions, manganese ions and phosphate ions. The invention also relates to the above cleaning agent composition itself and to a metal surface phosphate-coated by means of the above method and usethereof. 本发明涉及一种用于基本无镍磷化金属表面的方法，其中用以下组合物依次处理金属表面：i)包含至少一种水溶性硅酸盐的碱性含水清洁剂组合物，和ii)包含锌离子、锰离子和磷酸根离子的酸性含水且基本无镍的磷化组合物。本发明还涉及上述清洁剂组合物本身，并且涉及通过上述方法经磷酸盐涂覆的金属表面及其用途。
