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[P_(44414)][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][BF_(4)])进行比较。结果表明:传统离子液体[BMIM][BF_(4)]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],[P_(44414)][Hip]润滑时摩擦副的磨损量分别为使用[BMIM][BF_(4)]润滑时磨损量的9.3%,5.3%,18.1%。Three ionic liquids based hippurate were synthesized:1-butyl-3-methylimidazolium hippurate([BMIM][Hip]),choline hippurate([CHO][Hip])and tributyltetradecylphosphonium hippurate([P_(44414)][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][BF_(4)]was selected as a comparison.The results showed that traditional ionic liquids[BMIM][BF_(4)]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[P_(44414)][Hip]were 9.3%,5.3%and 18.1%of the friction pairs worn by[BMIM][BF_(4)],respectively.
