Abstract: In gear boxes, the life of gears is increased by reducing the wear caused due to the friction between the rubbing surfaces of gears. This paper addresses on the study of the relative anti-wear property of nano garnet gear lubricant which are formulated by dispersing 0.25 wt%, and 0.50 wt% of nano garnet particles in commercially available SN500 grade gear lubricant oil through a standard two-step method. The anti-wear property of the lubricant is estimated by a four-ball wear test and is measured through the microscopic investigations on the surface texture modifications namely width of the wear ring and wear scar diameter. The width of wear ring is reduced to 3.83%, 6.39%, and the wear scar diameter is reduced to 6.1%, 2.44% due to the addition of 0.25 wt%, and 0.50 wt% of particle concentrations at a maximum applied load of 588N due to the rolling effect of nano garnet particles.
