摘要
The composite coating containing n-SiO2 particles was prepared by electro-brush plating and its contact fatigue life was examined by taking account of the effect of n-Cu particles on it. The results showed that fatigue life of the n-SiO2/Ni composite coating could exceed a million cycles and incorporation of n-Cu particles into the plating electrolyte greatly decreased the contact fatigue life of the coating. It was showed that the structure of the coating was presented as a continuous multilayer structure, leading to the initiation of fatigue cracks between layers and the propagation along the boundaries between the layers, and contact fatigue failure in less cycles.
