- 摘要:
- 针对铝合金零件电镀银层表面存在粗糙现象的故障，绘制因果图对铝合金电镀银的生产过程包括浸锌、电镀铜、化学镀镍、电镀银等过程进行了排查，查找了生产参数记录，现场了解了实际情况，进行了工艺试验。结果表明：本次故障原因是零件浸锌溶液老化所致，配制浸锌溶液后进行电镀银试验，零件表面无粗糙问题，解决了该故障问题。
- Abstract:
- ： In view of the rough surface of the silver plating layer on aluminum alloy parts ， a cause and effect diagram was drawn to check the production process of aluminum alloy silver plating ， including zinc dipping ， copper plating ， electroless nickel plating ， silver plating and so on. The production parameter records were searched ， the actual situation was understood on site ， and the process test was carried out. The results show that the fault was caused by the aging of the zinc-dipping solution of the parts. After preparing the zinc dipping solution ， the silver electroplating test was carried out ， and it was found that the surface of the parts was not rough ， which revealed that the problem was solved.
