Abstract

In this research we studied a tribological properties of engine lubricating oil (SAE 15W40) blended with anti-wear additives like Boron Nitride Nanoparticles (hBN) and Titanium Oxide (TiO₂) nanoparticles. The tribological tests were performed on a Four-Ball Extreme-Pressure Tester with the standard ASTM D2783. Wear test and load carrying capacity tests were carried out on eight prepared samples. This study using four ball tribotester shows that blending of TiO₂ and hBN nanoparticles in SAE 15W40 engine oil significantly reduces the friction and wear rate and hence improves the lubricating properties of SAE 15W40. Experiment shows that engine oil wear properties improved by 45%, Coefficient of friction is improved by 39%, and load carrying capacity is improved by 25% with respect to the base oil after blending with TiO₂ (0.3% of weight) and hBN (0.05% of weight). Also, ANOVA results provide strong statistical evidence supporting the hypothesis that the inclusion of hBN, either alone or in synergy with TiO₂, leads to a significant reduction in wear, as reflected by the reduced scar areas.
