Suryavanshi Shrikant Jagannath,  Dr. Abhang L.B.
To improve the lubrication property to reduce wear and tear nanoparticles are very useful. In this project mos2 nanoparticles are added to engine oil 10W30 & 5W40 and Tribological properties are investigated. Samples were prepared of varying percentage of mos2 nanoparticles in engine oil (0.25, 0.5, 0.75 and 1 wt. %). The wear and friction experiment was carried on three tribal Tribotester and the tests were performed with varying load, speed and varying concentration of nanoparticles in engine oil. The obtained results show that mos2 nanoparticles added in engine oil exhibits good friction reduction and anti-wear properties and also decreased the coefficient of friction by 21% and 51% at 0.4wt% concentration respectively, as compared with standard engine oil without mos2 nanoparticles. This tribological behavior is closely related to the deposition of nanoparticles on the rubbing surfaces. In addition, the topography of worn surfaces was analyzed by using Scanning Electron Microscopy (SEM).
