| Abstract: | The nickel based nano-diamond composite coating was prepared by eletro-brush plating. In the composite coating, the influence of nano-diamond on the microstructure, mechanical and anti-wear properties was investigated systematically. The result showed that the composite coating was in low internal stress, high microhardness under the dispersing strengthened effect of nanodiamond. The nano-diamond composite coating had the excellent anti-fretting and anti-wear properties under the condition of high load, room temperature. The anti-wear property of composite coating was four times of that pure nickel coating. |
