- 摘要:
- 本文针对陶瓷化学镀中活化过程采用贵金属钯盐或银盐的现状，研究了采用铜盐进行敏化和活化的方法，以节省贵金属降低生产成本。实验结果表明，经前处理后的陶瓷放入0.25 g·L-1的稀CuSO4溶液中，室温下浸泡处理1 min.，用自来水和蒸馏水清洗后，再放入24 g·L-1 CuSO4·5H2O溶液中室温下浸泡15 min.，随后放入pH为8~9的NaOH溶液中，浸泡20 min.，即完成敏化。将敏化后的陶瓷放入含18 g·L-1 NaOH和50 mL·L-1 HCHO溶液中，在65 ℃浸泡40 min，完成活化。活化后的陶瓷可进行传统的化学镀铜，铜镀层均匀，致密，有很好的晶体结构，与基体有良好的结合力。
- Abstract:
- In this paper, according to the current situation of using precious metal palladium salt or silver salt in the activation process of ceramic electroless plating, the method of using copper salt for sensitization and activation was studied, in order to save precious metal and reduce production cost. The results showed that the pretreated ceramics was immersed in 0.25 g·L-1 CuSO4 solution for 1 min at room temperature. After cleaning with tap water and distilled water, the pretreated ceramics was immersed in 24 g·L-1 CuSO4·5H2O solution for 15 min at room temperature. Then the ceramics were immersed in pH 8 ~ 9 NaOH solution for 20 min, and the sensitization was completed. The sensitized ceramics was put into the solution containing 18 g·L-1 NaOH and 50 mL·L-1 HCHO, and soaked at 65 ℃ for 40 min to complete the activation. The activated ceramics could be electroless plated with copper by traditional method. The copper coating was uniform, dense, with good crystal structure and good adhesion to the substrate.
