- 摘要:
- 某型钢铁工件的电镀镉层出现针孔缺陷，分析确定，工件在完成吹砂后进行的钳工校形过程中，容易在其粗糙的表面附着污垢，且污垢附着较牢固，常规的清洗除油方法不能完全清洗干净，导致电镀镉层产生针孔缺陷。在工件前处理过程中增加碱煮工艺，可以将附着的污垢清洗干净，从而解决故障。
- Abstract:
- The pinhole defects appeared on the cadmium plating layer of a certain type of steel workpiece. The analysis result showed that the dirt could adhere easily to the rough surface of workpiece in the correcting process after blowing sand, and the adhesion of the dirt was strong, which resulted that it was hardly to clean by conventional cleaning methods. So that, the pinhole defects appeared on the cadmium layer. In order to solve the problem, the alkaline cooking process was introduced into the pre-treatment processes of the workpiece, the result showed that the dirt could be clean completely, and the electrodeposition malfunction was solved.
