摘　　要：为提高化学复合镀层的性能,采用纳米(SiC)P制备Ni-P-纳米(SiC)P化学复合镀层,较系统地研究镀液配方及各工艺参数对Ni-P-纳米(SiC)P化学复合镀层的影响,分析相应机理,同时对镀层进行热处理比较。实验结果表明:主盐、还原剂、温度、pH值、搅拌速率及(SiC)P加入量对Ni-P-(SiC)P镀层的沉积速率有较大影响,实验确定的最佳主盐浓度为28 g/L、还原剂浓度为30 g/L、施镀温度为(85±1)℃、pH值为4.5、搅拌速度为200 r/min、(SiC)P加入量为2 g/L。In order to improve the properties of electroless composite coating, the Ni-P- （SiC）p electroless composite coating added nano-（SiC）p was prepared and various parameters on the Ni-P- nano-（SiC）p coating were studied systematically. The corresponding mechanism was analyzed and the heat-treatment of coating was also compared. The experimental results show that： main salt, reducing agent, temperature, pH, stirring speed and （SiC）p amount of Ni-P-（SiC）p coating deposition and deposition rate had greater influence. It was confirmd that the optimum concentration of the main salt was 28 g/L, the concentration of the reducing agent was 30 g/L, the temperature was 85±1 ℃, the pH was 4. 5, the best stirring rate.200 r/mim;the optimal amount of particles：2 g/L.
