【摘要】：以环氧树脂为黏结剂,聚四氟乙烯(PTFE)为固体润滑剂,MoS_2为填料,采用空气喷涂法在GCr15钢基体上制备PTFE基减摩耐磨涂层,利用往复式摩擦磨损试验机测试了涂层的摩擦磨损性能,并采用正交试验法对固化温度、固化时间、喷枪压力等喷涂工艺参数进行了优化。结果表明:影响PTFE基减摩耐磨涂层摩擦学性能的喷涂工艺参数的主次顺序为喷枪压力、固化时间、固化温度;当固化温度为120℃、固化时间为60 min、喷枪压力为0.3 MPa时,涂层的平均摩擦因数为0.106,磨损体积为0.001 5mm~3,此时摩擦学性能最优。
[Abstract]:Using epoxy resin as binder, polytetrafluoroethylene (PTFE) as solid lubricant and MoS_2 as filler, PTFE based antifriction and wear resistant coating was prepared on GCr15 steel substrate by air spraying method. The friction and wear properties of the coating were tested by reciprocating friction and wear tester. The spray process parameters such as curing temperature, curing time and spray gun pressure were optimized by orthogonal test. The results show that the primary and secondary order of spraying parameters affecting the tribological properties of PTFE based antifriction and wear resistant coatings is gun pressure, curing time and curing temperature, and when the curing temperature is 120 鈩，
