双咪唑阳离子结构离子液体的高温摩擦学性能研究

Tribological Performances of Dicationic Ionic Liquids at Elevated Temperature

  • 摘要: 合成了含有双咪唑阳离子结构的离子液体1,6-二(3-己基咪唑)亚己基六氟磷酸盐,测定了其黏度和密度;采用钢/锡青铜摩擦副,在SRV摩擦磨损试验机上评价了该离子液体的摩擦磨损性能,并添加苯并三氮唑抑制摩擦过程中的腐蚀作用;采用扫描电子显微镜(SEM)和X射线光电子能谱(XPS)分析锡青铜表面磨斑处的表面形貌和化学状态. 结果表明:苯并三氮唑能够抑制双咪唑阳离子六氟磷酸盐的黏着磨损和摩擦腐蚀,摩擦副表面与离子液体在摩擦化学反应中形成含有Cu2O和CuO的边界润滑膜.

     

    Abstract: Ionic liquid 1, 6-bis (3-hexylimidazolium-1yl) hexylene hexafluorophosphate was synthesized. The kinetic viscosity and mass density of the ionic liquid were determined. The tribological performance of the ionic liquid for steel/Cu-Sn alloy was evaluated on an Optimol SRV oscillating friction and wear tester under ambient conditions. Benzotriazole was used as lubricant additive in ionic liquid to inhibit tribo-corrosion from Ionic liquid 1, 6-bis (3-hexylimidazolium-1yl) hexylene hexafluorophosphate . The worn surfaces on Cu-Sn alloy disc were analyzed by scanning electron microscope (SEM) and X-ray photoelectron spectroscopy (XPS). SEM results show slight abrasion and tribo-corrosion on the worn surfaces when BTA was used. XPS results indicate boundary lubrication film was composed of Cu2O and CuO by the tribochemical reactions of ionic liquid with Cu-Sn alloy during the sliding process.
