ENHANCEMENT OF TRIBOLOGICAL PROPERTIES OF LUBRICATING OILS USING CUO AND NIO NANOMATERIALS

Abstract

This paper aims to understand the tribological properties of lubricant oils containing CuO and NiO nanoparticles. The synthesized CuO and NiO nanoparticles were characterized using XRD, SEM,EDAX and IR spectral technics. XRD results revealed that CuO and NiO nanoparticles exhibited in the monoclinic and cubic phase respectively and kinematic viscosity studies indicated that the base oils obtained by catalytic dewaxing with hydrocracking and hydro finishing isodewaxing technology is better than extraction with hydro dewaxing technology. The High-Frequency Reciprocating Rig and Four balls wear and scar analysis emphasized that the addition of CuO and NiO nanoparticles effectively reduced the wear scar properties of MB150 and MB500 base oil samples. This study is more useful for the lubricant manufacturer for its selection of base oils and their formulations.
