| 摘 要： | 为改善Ni-P化学镀层的性能,采用化学复合镀的方法在镀层中添加了爆轰合成超微金刚石(Ul-trafine Diamond,UFD).研究了复合镀层的形成机理及镀液中UFD含量对复合镀层显微硬度及耐磨性的影响规律.实验用UFD众数粒径为114.6 nm.镀层显微硬度采用国产71型显微硬度仪进行检测,耐磨性采用国产MM200型磨损试验机进行检测.结果表明:随着镀液中UFD的加入,Ni-P合金粒子会以UFD颗粒为核心形成硬度较高的"包覆球"."包覆球"沉积到镀件表面形成复合镀层.复合镀层的显微硬度及耐磨性均随镀液中UFD含量的不同呈规律性变化.与Ni-P化学镀层相比,当镀液中UFD含量为0.8 g/L时,复合镀层显微硬度可提高0.6倍;当镀液中UFD含量为1.0 g/L时,复合镀层耐磨性可提高4.8倍.
