采用黏接固体润滑涂层法，以聚四氟乙烯为润滑剂，利用喷涂方式在试样上制备2种PTFE 基固体耐磨涂层，并采用HSR-2M型高速往复式摩擦磨损试验机对其摩擦学性能进行研究。研究结果表明，水性全氟涂层的摩擦因数不稳定且明显高于油性全氟；随着固化条件的改变，涂层的摩擦因数和磨损量也出现不同程度的变化；当采用油性全氟为润滑剂，固化温度为260℃，固化时间为30 min时，PTFE基耐磨涂层的摩擦因数和磨损量均最小，此时涂层的摩擦学性能最优。

Based on the bond solid lubricant coating method,two kinds of PTFE base solid wear-resisting coatings were prepared on the disc sample by spraying method and using PTFE as solid lubricant,and their tribological properties were investigated by HSR-2M high-speed reciprocating tribo-tester.The results show that the friction coefficient of water-based perfluorinated coating is unstable and apparently higher than that of oily perfluorinated coating.Friction coefficient and wearing capacity of the coatings are changed at a different degree along with the change of the curing conditions of the coat-ings.When using oily perfluorinated compound as solid lubricant and selecting the curing temperature of 260 ℃ and the curing time of 30 min,the prepared PTFE base wear-resistant coating has the lowest friction coefficient and wearing capac-ity,and the optimal tribological properties.
