摘要

研究了石墨烯和抗磨二烷基二硫代磷酸锌(ZDDP)的摩擦学效应。摩擦试验是在摩擦试验机上进行的，该试验机作为一个滚珠和圆盘组合在摩擦滑动运动中运行。试验是在10牛的载荷下进行的，滑动距离为1000米。试验采用TiAlN涂层HS6-5-2C钢盘和100Cr6钢球。用聚烯烃油PAO 8与石墨烯和/或ZDDP在欠润滑条件下进行了试验。利用扫描电镜研究了TiAlN涂层的化学成分，并观察了涂层盘和球上的磨损痕迹。用干涉式共聚焦显微镜对摩擦试验前后试样的几何结构进行了分析。结果表明，ZDDP和石墨烯的加入对聚烯烃油的摩擦系数有降低作用。

EVALUATION OF THE EFFECTS OF ZDDP AND GRAPHENEADDITIVES IN PAO 8 OIL ON THE TRIBOLOGICAL PROPERTIESOF TIALN COATING

This paper investigates the tribological effects of graphene and anti-wear zinc dialkyl dithiophosphates(ZDDP). Friction tests have been carried out on a tribological tester which operates as a ball and disc assemblyin a frictional, sliding motion. Tests were carried out with a load of 10 N over a sliding distance of 1000 m.TiAlN coated HS6-5-2C steel discs, and 100Cr6 steel balls were used in the tests. Tests were conducted underlubrication conditions with poly()olefin oil PAO 8 with graphene and/or ZDDP. The chemical compositionof the TiAlN coating was studied using a scanning electron microscope, and the wear marks on the discs andballs were observed. The geometric structure of the samples was analysed before and after the friction testsusing a confocal microscope with interferometric mode. The results indicated that the addition of ZDDP andgraphene to the poly()olefin oil had an effect on reducing the friction coefficient.
