Re-evaluation of the properties of a selected lubricant after adding Zinc oxide as a Nanoadditive

Abstract

This study includes synthesis of ZnO nanoparticles in organic media using Oleylamine and Oleic acid. Then survey the effect of ZnO nanoparticles on the properties of lubricant oil, The result show that, addition of ZnO nanoparticles with concentration of 0.05 (wt%) improve flash point by 3% also reduce scar diameter by 3.12 % with respect to pure lubricant, While there are no effect on pour point, thermal stability and viscosity of pure lubricant. The investigation of morphology and structures of nanoparticles carried out by TEM, XRD, FT-IR.
