| titleOfInvention | Glucosaminic-acid cyanide-free gold-plating electroplating liquid and electroplating method thereof |
| abstract | The invention discloses a glucosaminic-acid cyanide-free gold-plating electroplating liquid and an electroplating method thereof. The electroplating liquid comprises 10-15 g/L of gold trichloride calculated based on gold, 80-104 g/L of a glucosaminate, 32-60 g/L of iminodiacetic acid and 1-5 g/L of glycine. The glucosaminate is taken as a coordinating agent, iminodiacetic acid is taken as an auxiliary coordinating agent, and the glucosaminate and iminodiacetic acid give play to synergic effect for improving the gold coordinating capability. Glycine is taken as a stabilizing agent and prevents the electroplating liquid from being oxidized under an acidic condition. Gold trichloride is taken as a gold main salt, and thus the obtained electroplating liquid possesses relatively good dispersing force and covering power, and is high in cathode current efficiency and excellent in performances. A plating layer obtained by employing the electroplating liquid for performing electroplating under an alkaline condition is low in porosity, high in brightness and good in plating-layer quality. |
