摘　　要：采用复合化学镀方法,在超硬材料立方氮化硼粉体表面成功地制备了不同SiC含量的(Ni-P)-SiC复合镀层。实验结果表明,立方氮化硼粉体经复合化学镀后,SiC颗粒均匀分布于Ni-P合金中,表面呈银白色,有金属光泽,镀层致密、均匀,部分表面凹凸不平,有利于增加与树脂基体的把持力。当镀液中ρ(SiC)为2g/L时,复合镀层表面最粗糙,凹凸度增加。With electroless composite plating,（ Ni-P） -SiC composite coating with different SiC particle content was successfully prepared on cubic boron nitride powders.The test results showed that after the electroless plating boron nitride powder surface appeared silver white color with metallic luster.The coating was dense and in uniform thickness.Partial surface of the coating was full of bumps and holes which could improve the retention of the coating with the resin matrix.The composite coating with the most suitable roughness could be obtained when 2g/L SiC particles was added in the plating bath during the composite plating.
