摘　　要：研究了表面活性剂对AZ31镁合金Ni-P-nano-Si3N4化学复合镀层形貌、镀速、镀层中nano-Si3N4颗粒的含量以及镀层硬度的影响。结果表明,采用阴离子表面活性剂,使Ni-P-Si3N4镀层的组织均匀且致密,镀层的硬度和沉积率都较高。The effects of surfactants on the surface morphology, deposition rote and hardness of AZ31 Ni-P-nano-Si3N4 composite coating were investigated. The results show that uniform structure, highest hardness and deposition rate of the composite coating can be obtained by anionic surfactant.
