Tribological Investigation of Bitter Almond Oil Containing TiO2 Nanoparticles as Additive

In the recent years, the environment friendly lubricants have been using worldwide. Vegetable oils-based lubricants are the best substitute of the mineral and synthetic lubricant. In view of this present study concerns on tribological investigation of bitter almonds oil containing TiO2 nanoparticles and Triton X-100 as surfactant.  Four different volume fractions of nanoparticles (0.01, 0.02, 0.03, and 0.04) used for nano lubricant formulation and the ratio of TiO2 nanoparticles and Triton X-100 is 2:1. The tribological investigation of formulated Bitte almond oil-based nano lubricant on Four ball tribotester using ASTM 4172B. Bitter almonds oils containing 0.02 vol. fraction nanoparticles showed minimum average wear scar diameter and coefficient of friction
