摘　　要：以E-44环氧树脂为基料,再加入纳米级的PTFE微粒以及定量的乙二胺交联剂制备了PTFE固体复合润滑膜,通过摩擦磨损实验和表面形貌测试探讨了PTFE的最佳添加量,并考察了石墨添加量对复合固体润滑膜的硬度等性能的影响。实验结果表明:PTFE固体润滑膜具有良好的摩擦性能,加入石墨粉末后其摩擦因数有所提高,其硬度明显提高,单位磨损量降低。The PTFE solid lubricant film was prepared by using E-44 epoxy resin,PTFE nanoparticles and a quantitative ethydiamine crosslinker as raw material.The appropriate adding amount of PTFE was obtained by the friction and wear experiment and the surface morphology test.The graphite powder was added into the reaction system to improve the film hardness.The experimental results show that PTFE solid lubricant film exhibits a good friction property,and by adding graphite powder,the friction coefficicent is increase...
