Tribological Properties of Plastic Lubricants in Compositions with Various Carbon Nanostructures

Abstract

The effect of carbon nanomaterials (CNMs) of various structures (multi-layered oxidized graphene, single-walled and multi-walled carbon nanotubes, schungite carbon nanoparticles) on the friction coefficient and scoring resistance of industrially manufactured imported and domestic plastic lubricant materials (PLMs) has been experimentally investigated. It is shown, that the addition of CNMs to domestic PLMs leads to an increase in durability, and the resulting effect on the friction coefficient depends on different factors, such as the type of base PLM, the structure of CNMs, the concentration of CNMs, and the load.
