Imidazolium-bis(salicylato)borate Ionic Liquids as Lubricant Additives: the Effect of Alkyl Chain Lengths on the Tribological Performance
摘要
Abstract
Seven environmental-friendly ionic liquids containing chelated organoborate anions having different alkyl chain lengths were synthesized and then evaluated as potential lubricant additives. The 1 H NMR, TGA and DSC were employed to characterized the structure and thermal properties of synthesized ionic liquids. The tribo-performacne were systematically studied by four-ball machine and SEM-EDX as well. The synthesized ionic liquids were found to be quite stable at room temperature and showed remarkable improvement in the anti-wear properties of the poly(ethylene) glycol(PEG200) lube base. The results showed that ionic liquids as additives significantly reduced the wear of PEG200, and particularly the variation in substituted alkyl chain length on the imidazolium ring monitored the degree of reduction in wear. C6 ImC8 BScB shows the excellent friction reducing properties among all the synthesized ionic liquids, the coefficient of wear scar diameter lubricated by PEG under 392 N corresponding reduced with mass fraction of 27. 49%.关键词
