Evaluation of Tribological Properties of Graphene Oxide Dispersed Paraffin Oil

This research study investigates the tribological behavior of ODA Graphene nano particles as lubricant additives in mineral based paraffin oil. All tests are performed under varying load and 0.2% w/w concentration of nano particles in lubricating oil using ball and disc configuration and four-ball testers. Experimental results state that small percentage of ODA Graphene is improving the friction, anti-wear properties and dynamic viscosity. Coefficient of friction in EHD and boundary regime is decreased by 75% and 61.8% respectively. The results are validated by using the Raman Spectroscopy of worn steel ball to confirm the presence of ODA graphene nano particles.
