Characterization of ZnO-TiO2 Hybrid Nano Based SAE 15W-40 Oil

Abstract

The main aim of the present investigation was to characterize the lubricant dispersed with ZnO-TiO₂ hybrid nanoparticles. The work includes a dispersion of nanoparticles with varying proportions of 0.02 to 0.08 with an incremental step of 0.02 wt. % of base oil. Further, the samples were used to study the thermo-physical properties.  The characterization result includes crystallinity and particle size of Zinc-oxide and titania nanoparticles, whereas the nano-based lubricant is characterized for its chemical compatibility, thermal conductivity, viscosity, and thermal stability. The result favors enhancing the thermo-physical properties of nano-based lubricant.
