利用不同长度碳链的脂肪醇合成3种多功能型极压抗磨剂——2,5-二巯基-1,3,4-噻二唑衍生物,考察其作为添加剂在复合锂基润滑脂中的摩擦学性能及抗氧化性能,利用扫描电子显微镜及X射线光电子能谱分别分析了磨痕表面形貌及表面化学成分。试验结果表明:合成的噻二唑衍生物都能有效提高基础脂的极压、抗磨、减摩及抗氧化性能;噻二唑衍生物在摩擦过程中发生了化学吸附及摩擦化学反应,在摩擦区域金属表面上形成了一层以硫化物为主,同时含有含氮小分子及铁的氧化物组成的复杂边界润滑膜,从而起到了良好的抗磨减摩的作用。 |

Three derivatives of 2,5-dimercapto-1,3,4-thiadiazoles with different carbon chains were synthesized,and their triboolgical properties and anti-oxidative performance as multifunctional additive in lithium complex grease were elvaluted.The surface topography and chemical constituent of friction surface after test were investigated by X-ray photoelectron spectroscopy(XPS),scanning electron microscope(SEM),and their anti-wear mechanism was analyzed.The results demonstrate that these compounds can greatly improve the antiwear,load-carrying and anti-oxidative performances of lithium complex grease.Because tribochemistry reaction occurs during friction and an boundary lubrication film is formed on the metal surface,the anti-wear and friction reducing properties are enhanced,and the extreme pressure capacity of the base grease is improved. |
