Abstract
The effect of carbon nanoparticles (graphene, single-walled and multi-walled carbon nanotubes and fullerene-containing nanomaterials) on tribological characteristics of industrial greases and motor oils is studied and the obtained results are discussed. It is shown that this effect depends not only on the carbon nanoparticle nature but also on the base material, reducing or increasing the frictional moment. The introduction of nanoparticles into industrial greases increases the limiting load of seizure and allows to use the tested greases doped with nanoparticles selectively depending on the requirements applied to a tribotechnical system. An engine oil with nanotribological compositions containing fullerene do not influence on the tribotechnical properties of the studied systems.
