| 摘 要： | 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.

| Abstract: | A new mixed phosphate was prepared and characterized by Fourier transform infrared spectroscopy (FT-IR). Tribological properties of the new phosphate as an additive of ester oil for a steel/steel contact were investigated on an optimal SRV friction and wear tester. The morphology and element analysis of the worn scar surfaces were characterized by scanning electron microscopy (SEM) and X-ray photoelectron spectroscopy (XPS), respectively. The experimental results showed that the novel additive showed excellent anti-wear and load-carrying capacity. XPS results showed that a boundary lubricating film was formed on the steel worn surface by physical and chemical adsorption, while tribochemical reaction of the additive with the steel surface was involved at elevated temperature to generate a boundary lubricating film containing fluoride, chloride and phosphate. This contributed to increased load-carrying capacity and reduced wear. |
