Abstract (en)
[origin: DE19933189A1] The invention relates to a method for the anticorrosive treatment or post-treatment of bright or phosphatized steel surfaces, galvanized or alloy-plated steel or aluminum and its alloys. According to the inventive method, the metal surfaces are contacted with an aqueous solution that contains 0.05 to 10 g/l complex fluorides of boron, silicon, titanium and/or zirconium and one or more phosphatization accelerators, preferably selected from m-nitrobenzene sulfonate ions, N-methylmorpholine-N-oxide and hydroxylamine.
