Key Points

The aim is to assess how dispersing lithium grease with hybrid nano titanium and silicon oxides affects the friction coefficient.
Utilized aluminum disc and stainless steel pin setup for friction tests.
Applied hybrid nano titanium and silicon oxides at five different concentration levels up to 8 wt. %.
Conducted experiments to evaluate friction characteristics with different concentrations.
At 6 wt. % and 8 wt. %, hybrid nano oxides significantly improved friction characteristics.
The friction coefficient was enhanced due to the self-repair capabilities of the hybrid nano oxides on contact surfaces.

Abstract

This paper examines the influence of dispersing lithium grease by hybrid nano titanium and silicon oxides on friction coefficient. Nano titanium, silicon and hybrid nano oxides at five concentration levels were used to disperse the lithium grease. Experiments were carried out using an aluminum disc sliding against stainless steel pin. Results show that, nano oxides particles have shown good friction characteristics and even at concentrations of 6 wt. % and 8 wt. %. Moreover, friction coefficient is improved because of the self-repair role of hybrid nano oxides particles on contact surfaces.
