Abstract

At present, carbon nanomaterials are widely used to improve the tribotechnical characteristics of various materials, including liquids. In the presented article, the issues of improving the tribotechnical characteristics of lubricating liquid media are considered. These liquids were modified with hybrid carbon materials, which are a mixture of graphite, graphene, and carbon nanotubes. Carbon mixtures of nanoparticles were obtained by the method of self-propagating high-temperature synthesis. It has been established that the introduction of mixtures of nanocarbon particles into a liquid lubricating medium significantly changes the tribological and viscosity characteristics. The most significant reductions in the values of the friction coefficient of modified liquids are observed at low concentrations of the carbon nanomodifier.
