合成了一系列金属氯化物封端线性低聚磷嗪衍生物,利用SRV摩擦磨损试验机评价了其作为润滑剂对钢/钢摩擦副的润滑效果.结果表明,合成的线性低聚磷嗪衍生物作为润滑剂的摩擦学性能与侧链取代基和金属离子密切相关.所考察润滑剂的抗磨性能随着金属离子半径的增加呈现增强趋势,但铁盐例外.通过扫描电子显微镜和X射线光电子能谱仪观察分析了钢盘磨损表面的形貌和元素化学状态,发现金属氯化物封端线性低聚磷嗪衍生物在摩擦过程中形成了由含有机氟化物、氮的氧化合物、Fe3(PO4)2等组分的物理吸附膜和摩擦化学反应膜构成的复合润滑膜,从而有效提高了抗磨减摩能力.
A series of metal chloride terminated linear oligo-phosphazene derivatives were synthesized and their lubricity to steel / steel friction pairs was evaluated by SRV friction and wear tester.The results showed that the synthesized linear oligo-phosphazine derivative The tribological properties of the lubricant as a lubricant are closely related to the side-chain substituents and the metal ions.The anti-wear properties of the investigated lubricants show an increasing tendency with the increase of the radius of the metal ions, except for the salt of iron.With scanning electron microscopy and X-ray The morphology and elemental chemical state of the wear surface of the steel disc were observed and analyzed by photoelectron spectrometer. It was found that the metal chloride terminated linear oligo-phosphazene derivative formed by the reaction of organofluoride, nitrogen containing oxygen compounds, Fe3 (PO4) 2 and other components of the physical adsorption film and the friction chemical reaction membrane composition of the lubricating film, which effectively improve the anti-wear anti-friction ability.
