摘要： A process for improving the wear resistance and enhancing the black color of a black or blue rhodium-plated article is disclosed. In this process the rhodium-plated article is subject to anodic electrolysis, said electrolysis being carried out in a bath comprising one or more selected ingredients with a direct current of a current density of 0.004 to 20 A/dm 2 and a bath temperature of 20 to 60°C for 3 to 60 minutes.
