Abstract

The chemical-plating quality of random-loaded small parts depends on the gap control between the parts in the bath. In this study, the plating characteristics for the screw motion of a basket in a bath were analyzed. This motion could be separated into parts for each, and the space for chemical reactions could be created, which improved its quality. The performance of the new technique was verified through experimental design and salt spray tests. The experimental results showed that the main factors that affected quality were temperature and plating solution concentration. In particular, the white rusting generated time of the screw motion method was longer than that of the conventional method.
