Titanium oxide nano-particles as anti-wear and friction-reduction additives in lubricating oil

Abstract

This study examined the tribological behavior of titanium oxide nanoparticles as additives in mineral based multigrade engine oil. All tests were performed under variable load and concentration of nanoparticles in lubricating oil. The friction and wear experiments were performed using pin on disc tribotester. It was demonstrated that the nanoparticles as additives in lubrication can effectively improve the lubricating properties. This was because the nanoparticles go into the friction zone with the flow of lubricant, and then the sliding friction changed to rolling friction with a result of the reduction of the friction coefficient.
