| titleOfInvention | METHOD FOR PHOSPHATING METAL SURFACES |
| abstract | A process is disclosed for phosphatizing metallic surfaces, in particular electrolytically or hot dip galvanized steel band surfaces, by dip or spray processing the metallic surfaces with acid, aqueous phosphatizing solutions, whereas the workpieces are cathodically treated at the same time with direct current. The process is characterized by (a) the use of phosphatizing solutions that contain the following components: Zn<2+> cations in a range from 0.1 to 5 g/l; PO4<3-> anions in a range from 5 to 50 g/l; NO3- anions in a range from 0.1 to 50 g/l, as well as Ni<2+> cations in a range from 0.1 to 5 g/l, and/or Co<2+> cations in a range from 0.1 to 5 g/l; (b) the observance of the following conditions: pH value of the phosphatizing solutions in a range from 1.5 to 4.5; temperature of the phosphatizing solutions in a range from 10 to 80 DEG C; duration of treatment in a range from 1 to 300 sec; (c) simultaneous cathodic treatment of the workpiece during phosphatization with a direct current having a density in a range from 0.01 and 100 mA/cm<2>. |
