| titleOfInvention | Method for electrolytically passivating outermost chromium or outermost chromium alloy layer to increase its corrosion resistance |
| abstract | The invention relates to a method for electrolytically passivating the outermost chromium or outermost chromium alloy layer to increase its corrosion resistance. The method includes the following steps: (i) providing a substrate including the outermost chromium or outermost chromium alloy layer. (Ii) providing or manufacturing an acidic passivation aqueous solution containing trivalent chromium ions, phosphate ions, one or more organic acid residue anions, (iii) contacting the substrate with the passivation solution and acting as the passivation solution A current is passed between the substrate of the cathode and the anode, so that the passivation layer is deposited on the outermost layer. In the passivation solution, the trivalent chromium ions are composed of hydrogen peroxide and an organic reducing agent in the presence of phosphoric acid through At least one reducing agent of the group is obtained by chemical reduction of hexavalent chromium with the limitation that one or more organic acid residue anions first appear in the passivation solution during or after the chemical reduction. |
