Tribological improvement using Ti3C2Tx MXenes and/or CaCO3 nanoparticles as lubricant additives

The main goal of this work is the tribological characterization of low viscosity nanolubricants, PAO8 base oil containing Ti3C2Tx MXenes and/or functionalized CaCO3 (CaCO3-OA) nanoparticles as additives. Friction enhancements were reached with CaCO3-OA nanolubricants with maximum reductions of 44 %...
