"Evaluation of Ionic Liquids as Lubricants";
Journal of Microengineering and Nanoelectronics, 1 (2010), 1; 29 - 34.



English abstract:
15 pure ionic liquids of varying chemical structures were evaluated as lubricants for steel-steel contact. Friction and wear behaviour of the ionic liquids were investigated by an oscillating tribometer with ball-on-disk geometry at 30, 100 and 170 C. The results have been compared with four reference lubricants and have been found to be partly superior for ionic liquids. Thermal stability and corrosiveness to copper were tested in long-term tests under static conditions at 100 and then at 150C. Most ionic liquids were characterised by acceptable to excellent thermal stability at 100C. At 150C, a few ionic liquids fulfilled requirements of negligible degradation resulting in low evaporation rates and constant physico-chemical properties. Some copper specimens have suffered from severe attack whereas several ionic liquids showed no corrosive behaviour. Varying chemical composition was expressed in significant differences in physico-chemical, tribological and long-term behaviour of the investigated ionic liquids.
