采用均匀试验设计方法 ,利用摩擦磨损试验机及扫描电子显微镜 (SEM)对火焰喷涂尼龙 10 10 /石墨复合涂层的干摩擦磨损性能进行了测试 ,并利用SPSS统计软件对实验结果进行了回归分析 ,得到了复合涂层的干摩擦系数及磨损量与PV值之间的数学模型。结果表明 :在实验速度 ( 0 2 6～ 0 92m/s)及实验载荷 ( 10 0～ 3 5 0N)范围内 ,复合涂层的干摩擦系数为 0 3 95～ 0 419;在实验时间 ( 2 0min)内 ,涂层的磨损量为 3 0～ 14 5mg ,均优于纯尼龙涂层。涂层的摩擦磨损机制主要为疲劳磨损和黏附磨损
The friction and wear properties of flame-sprayed nylon 10 10 / graphite composite coating were tested by means of a uniform test design method using a friction and wear tester and a scanning electron microscope (SEM). The experimental results were analyzed by SPSS statistical software The mathematical model between the dry friction coefficient and the wear amount and the PV value of the composite coating was obtained. The results show that the dry friction coefficient of the composite coating is 0 3 95 ~ 0 419 at the experimental speed (0 2 6 ~ 0 92m / s) and experimental load (10 0 ~ 350N) 0min), the coating wear amount of 30 ~ 14 5mg, are better than pure nylon coating. The friction and wear mechanism of the coating is mainly fatigue wear and adhesion wear
