摘　　要：研究了化学复合镀Ni-P-金刚石镀层的耐磨性。通过观测热处理前后的金相组织、硬度变化,对比了热处理前后镀层的耐磨性。结果表明:采用合适的工艺条件,可获得金刚石微粉分布均匀的镀层,经热处理后,镀层硬度可达901 HV0.2,且镀层与基体结合力良好,耐磨性大大提高。Abrasion prtformance of Ni-P- diamond composite coating was studied. The microstructure and microhardness were measured, and the wear resistance was contrasted before and after heat treatment. The results show that the distribution of micro-diamond particle is uniform within the composite films. After heat treatment, the microhardness is 901 HV, the coating has good adhesion, and the abrasion performance is greatly improved.

关 键 词：化学复合镀 硬度 耐磨性
