Synthesis, Characterization and Tribological Properties of Imidazol Cheat Boron Ionic Liquids with Different Alkyl Length
摘要
Abstract
Four environmental-friendly ionic liquids containing imidazol cations with different alkyl chain lengths and bis(salicylato)borate anion were synthesized.Their structures were characterized by NMR, ICP-OES and tribo-performance was studied on four-ball machine and SEM-EDX as well.Tribological properties are largely influenced by alkyl chain lengths.CnMImBScB(n=2,4,6,8) have excellent friction reducing properties, in particular, the coefficient of friction and wear scar diameter lubricated by PEG200 under 392N reduce 58.46% and 20.5%, respectively, when mass fraction of 2% C8MImBScB is introduced.The elemental mapping of worn surfaces reveal that the formation of cheat boron ionic liquids constitutes a tribo-chemical thin film, which not only protect the contact surface against the wear at some extent but also reduces the friction significantly.关键词
