摘　　要：通过单因素分析和正交实验研究纳米SiC,PTFE乳液与表面活性剂FC-4对化学复合镀Ni-P-纳米SiC-PTFE的影响。结果表明:对复合镀层磨损量影响最大的是SiC,对摩擦系数影响最大的是PTFE,对镀速影响最大的是表面活性剂FC-4。最佳工艺为:纳米SiC 8 g/L,PTFE乳液2 mL/L,表面活性剂FC-4 0.3 g/L。此时能获得最小磨损量(0.004 695 mm3),较低的摩擦系数(0.49),适中的镀速(6.3 mg.cm-2.h-1)。The effects of nano SiC,PTFE emulsion and surfactant FC-4 on Ni-P-nano SiC-PTFE electroless composite plating were investigated by single factor analysis and orthogonal experiment.The results show that the greatest impact on the wearing capacity,friction coeffcient and plating rate of the composite coating is from SiC,PTFE and surfactant FC-4 respectively.The optimal process is： nano SiC 8 g/L,PTFE emulsion 2 mL/L and surfactant FC-4 0.3 g/L.With this process,the smallest wearing capacity（0.004 695 mm^3）,lower friction coefficient（0.49） and modest plating rate（6.3 mg·cm^-2·h^-1） can be obtained.
