Abstract

Investigations on the potential use of ionic liquids (ILs) as additives in lubricants have increased in the recent past. Low miscibility of ILs in the non-polar oils is a major obstacle in maintaining an optimum lubrication performance. This article focuses on the use of Trihexyltetradecyl phosphonium bis (2,4,4- trimethylpentyl) phosphinate as an additive in mineral base oil. Wear rate was estimated for different concentrations of IL at constant load and temperature. Coefficient of friction was found to be least in 3% when compared to 5% and 1% by volume concentration. This was further validated by the SEM and AFM analysis carried out. ZDDP was blended with the IL and the additive interaction was also studied.
