| Outline of Final Research Achievements |
By using ILs as engine oil, the following interest lubricating system can be expected. The high-pressure CO2 produced by combustion of fuel gas is absorbed into an IL used as a lubricant. This CO2 absorption to the IL can make friction lower with thin tribo-film made of iron carbonate and/or bicarbonate. In this work, to study a possibility of ILs as new lubricants with such interest function, we evaluated the lubrication properties of ILs absorbed CO2 by ball-on-disk friction tests with SUJ2 steel ball and disk.
It was observed that 1,3-dimethylimidazolium dimethylphosphate ([C1C1im][dMp]) showed better lubricity than conventional synthesized hydrocarbon oil. The effect of absorbed CO2 is not remarkable in anti-wear performance, however it is noteworthy that a serious elevation of friction coefficient at early stage in test duration lubricated with [C1C1im][dMp] was suppressed in case with CO2 absorbed [C1C1im][dMp].
