由氯乙醇,三氟乙醇和三氯氧磷合成了三氟乙基氯乙基磷酸酯(FPC),采用傅里叶变换红外光谱仪(FT-IR)对其结构进行了表征;在微动摩擦磨损试验机(SRV)上评价了其作为酯类润滑油添加剂的摩擦学性能;采用扫描电子显微镜(SEM)和X射线光电子能谱仪(XPS)分析了摩擦表面的形貌及化学状态.结果表明:FPC作为添加剂对钢/钢摩擦副具有良好的极压抗磨性能;FPC在钢磨损表面形成了含有氟化物,氯化物及磷酸酯的混合边界润滑膜,从而有效地提高了润滑油的承载能力和抗磨性能.
Trifluoroethyl chloroethyl phosphate (FPC) was synthesized from chloroethanol, trifluoroethanol and phosphorus oxychloride. Its structure was characterized by Fourier transform infrared spectroscopy (FT-IR) Tribological properties of esterified lubricant additives were evaluated on a wear tester (SRV), and the morphology and chemical state of the friction surfaces were analyzed by scanning electron microscopy (SEM) and X-ray photoelectron spectroscopy (XPS) .Results The results show that FPC has good extreme pressure and antiwear property to the steel / steel friction pair as an additive. FPC forms a mixed boundary lubricating film containing fluoride, chloride and phosphate on the steel wear surface, which effectively improves the lubricating oil Carrying capacity and anti-wear performance.
