Abstract (en)
[origin: WO2016162423A1] The invention relates to a method for, essentially, nickel-free phosphating a metal surface, in which a metal surface, optionally after cleaning and/or activating, is initially treated with an acidic aqueous phosphating composition which contains zinc ions, manganese ions and phosphate ions, is optionally rinsed and/or dried, and then is treated with an aqueous post-rinsing composition which comprises at least one type of metal ions selected from the group consisting of ions from molybdenum, copper, silver, gold, palladium, tin, antimony, titanium, zirconium and hafnium and/or at least one polymer selected from the group consisting of polymer classes of polyamines, polyethylenamines, polyanilines, polyimines, polyethylenimines, polythiophenes and polypryroles and to the mixtures and copolymerisates thereof. The invention also relates to the phosphating composition as well as to the post-rinsing composition which is essentially nickel-free.
