Anti Friction Properties of Motor Oil Dispersed with WS₂ and MoS₂ Nanoparticles

Abstract:

This works presents a study on anti friction properties, of fully formulated SAE 20W 40 grade motor oil dispersed with surface modified WS₂ and MoS₂ nanoparticles. WS₂ and MoS₂ particles of 0.05 wt. % and 0.1 wt. % have been dispersed in SAE 20W 40 motor oil by Sonication and tested for tribological behavior on pin on disc apparatus as per ASTM G99 standards. The friction coefficient values for base oil and oil dispersed with WS₂ and MoS₂ nanoparticles have been evaluated and compared to obtain the performance analysis. Performance graphs have plotted for the base oil and oil dispersed with nanoparticles for comparison. The oils with dispersed nanoparticles have shown enhanced performance in comparison to the base oils in terms of anti friction properties.
