摘要/Abstract

摘要： 设计开发了3种马尿酸盐类离子液体：1-丁基-3-甲基咪唑马尿酸盐离子液体[BMIM][Hip]、胆碱马尿酸盐离子液体[CHO][Hip]和三丁基十四烷基鏻马尿酸盐离子液体[P₄₄₄₁₄][Hip]，通过电化学和摩擦学方法分别考察了这3种离子液体对低碳钢的腐蚀性，及其作为润滑剂对钢/钢摩擦副的摩擦学性能，并与传统1-丁基-3-甲基咪唑四氟硼酸盐离子液体（[BMIM][BF₄]）进行比较。结果表明：传统离子液体[BMIM][BF₄]对低碳钢的腐蚀性较强；合成的3种离子液体对低碳钢的腐蚀性均非常弱，其中[CHO][Hip] 对低碳钢的腐蚀性最弱；此外，合成的3种离子液体在钢/钢摩擦副上均表现出优异的摩擦学性能，使用[BMIM][Hip]，[CHO][Hip]，[P₄₄₄₁₄][Hip]润滑时摩擦副的磨损量分别为使用[BMIM][BF₄]润滑时磨损量的9.3%，5.3%，18.1%。

Abstract: Three ionic liquids based hippurate were synthesized: 1-butyl-3-methylimidazolium hippurate ([BMIM][Hip]), choline hippurate ([CHO][Hip])and tributyltetradecylphosphonium hippurate ([P₄₄₄₁₄][Hip]). The corrosion of the three ionic liquids to mild steel and the tribological performances of the three ionic liquids as lubricants the steel/steel friction pairs were investigated by electrochemical measurements and frictional tests, respectively. The traditional ionic liquids [BMIM][BF₄] was selected as a comparison. The results showed that traditional ionic liquids [BMIM][BF₄] had strong corrosion to mild steel. The three synthesized ionic liquids had very low corrosion to mild steel, and [CHO][Hip] had the least corrosion. The three synthesized ionic liquids showed excellent tribological performances the steel/steel friction pairs, [BMIM][Hip], [CHO][Hip] and [P₄₄₄₁₄][Hip] were 9.3%, 5.3% and 18.1% of the friction pairs worn by [ BMIM ][ BF₄], respectively.
