摘　　要：利用一步法合成了一种季磷盐氨基酸离子液体水基润滑剂添加剂,并与纯水进行了对比。采用微动摩擦磨损试验机,考察了不同浓度条件下水溶性离子液体作为水添加剂对钢/钢摩擦副的摩擦学性能,采用扫描电子显微镜(SEM)及能量色散X射线光谱仪(EDX)对磨斑表面进行了分析。结果表明:在相同的实验条件下,随着添加剂质量浓度的增加,其减摩抗磨性能也相对增加,并且趋于稳定。对所得添加剂季磷盐氨基酸离子液体摩擦学性能进行了系统研究。与传统的水性润滑添加剂相比,制备简单,具有优异的摩擦学性能和良好的水溶性。A quaternary phosphonium salt amino acid ionic liquid water-based lubricant additive is synthesized by one-step method,and compared with pure water.The tribological properties of water-soluble ionic liquids as water additives to steel/steel friction pairs are investigated by fretting friction and wear tester.The wear scar surface is analyzed by scanning electron micros(SEM)and energy dispersive X-ray spectrosmeter(EDX).The results show that under the same experimental conditions,as the mass concentration of the additive increases,the antifriction and antiwear properties of the additive increase relatively and tend to be stable.The tribological properties of the quaternary phosphonium salt amino acid ionic liquid of the additive are systematically studied.They are simple to prepare,have excellent tribological properties and good water solubility compared with traditional water-based lubricant additives.
