Study on Brush Composite Plating Ni-Fe-diamond Technology

Composite brush plating is one of the important aspects of brush plating. The coating of Ni-Fe-diamond composite brush plating with high density and wear-resistance has broad application prospect. Based on the experiment, some factors, like voltage, temperature and relative velocity, which influenced the performance of the coating, such as contents of diamond, deposition rate and relative wear resistance, were discussed in this paper. Optimal technical parameters of the coating with high diamond content and high-wear-resistance were obtained, the plating voltage, temperature and relative velocity are 9～11 V, 45～55 ℃ and 10～15m/min,respectively.
