The aim of this research is to study the influence of adding Multi- Walled Carbon Nanotube (MWCNTs) and graphene nano sheet (GNS) on the rheological behavior, tribological properties and thermal conductivityof calcium grease. The results show that the grease with CNTs and GNS exhibit good performance in anti-wear, friction reduction, load carrying capacity and extreme pressure properties with only 3% wt. The rheological behaviors were evaluated with a Brookfield. The results indicate increases stress and apparent viscosity.
