Abstract

Friction is one of major concern in mechanical movement while the lubri- cant is one of solution to counter it. The additive of nanoparticles in lubricant may improve its tribological performance. The current study focusses on the effect of SiO2 and TiO2 nanoparticles as additive in PVE lubricant. The new solution namely nanolubricant was prepared at three different concentrations. The nanolubricants were characterized using TEM and itsstability was evaluated up to 30 days. Four-ball method was used to determine the effect of nanoparticle concentration on coefficient of friction (COF) and wearscar diameter (WSD). The resultsreveal that nanoparticle additive provide betterCOF at low volume concentration. TheCOF for nanolubricant at volume concentration less than 0.010% for TiO2 and less than 0.005% for SiO2 attained lower than pure PVE lubricant. The results for WSD also were in agreement with the trend of COF. Therefore, the nanolubricant has potential to provide better friction coefficient performance for lubrication application.
