| titleOfInvention | Method for electrolytically passivating the surface of silver, silver alloy, gold, or gold alloy |
| abstract | The present invention relates to a method for electrolytically passivating a surface of silver, a silver alloy, gold, or a gold alloy, the method comprising: (i) providing a substrate comprising said surface; (ii) providing an aqueous passivating solution, said aqueous passivating solution comprising: - trivalent chromium ions, and - providing said aqueous passivation solution comprising one or more species of carboxylic acid residual anions; (iii) contacting the passivation solution with the substrate and passing an electric current between the substrate as a cathode and an anode to electrolytically deposit a passivation layer at the surface; The trivalent chromium ions form a molar ratio in the range of 1:10 to 1:400 for all species of carboxylic acid residual anions. |
