| Popis: | This work deals with the tribological properties of recently described mixtures of nanoparticles (NPs) and ionic liquids (ILs), specifically mixtures of SiO 2 (silica) nanoparticles and 1-butyl-3-methylimidazolium (trifluoromethysulfony)imide. Friction force profiles, kinetic friction coefficients, friction traces, rheological properties, and wear behavior of these mixtures were compared with that of the pristine ionic liquids at various concentrations of nanoparticles for a tribo-pair of stainless steel ball and a steel surface. It was shown that NP concentration significantly influences the tribological properties of the NP-IL mixtures: the friction coefficient for the optimum NP concentration (0.05 wt%) was ~35% less than that for high NP concentrations (>3 wt%) and 25% less than that for low NP concentrations ( |
