| Abstract: |
| The craftwork of composite chemical Ni-plating on the roll bearing-steel was studied, the microstructure and phase structure of Ni and the composite film were analyzed by SEM, the micro-hardness and wear resistance were measured with HXZ-100 micro-sclerometer and LY71-XM-200 tWe surface morphology measure, and the wear mechanism was analyzed. The results show that the structure of plating-layer is cystiform protuberance before the heat treatment, the micro-hardness is 430.6HV; after it, the plating-layer is single nano-diamond composite film, uniformity and felsite, the micro-hardness is 1807.OHV, and greatly enhances the wear resistance; the wear resistance of platinglayer would take change along with different content of nano-diamond in the liquid ; the plating-layer doesn't fall off under 19.6 N stress; it shows the excellent adhesion reaches the exterior capability of rolly bearing. |
