| titleOfInvention | A method for electrolytically passivating a surface of silver, silver alloy, gold, or gold alloy |
| abstract | The present invention relates to a method for electrolytically passivating a surface of silver, silver alloy, gold, or gold alloy, the method comprising the steps of (i) providing a substrate comprising said surface, (ii) providing an aqueous passivation solution comprising - trivalent chromium ions, and - one or more than one species of carboxylic acid residue anions, (iii) contacting the substrate with said passivation solution and passing an electrical current between the substrate as a cathode and an anode such that a passivation layer is electrolytically deposited onto said surface, wherein the trivalent chromium ions with respect to all species of carboxylic acid residue anions form a molar ratio in the range from 1:10 to 1:400. |
