Abstract
The paper presents the results of a study of the sliding friction process of a porous material based on iron impregnated with lubricating oil with dispersed particles of fluorinated graphene.
It is established that the regularities of the kinetics of external sliding friction have a sigmoidal and sigmoidal-linear character. Experimental results have been obtained showing that with an
increase in the concentration of aggregates from flakes of fluorinated graphene in the lubricating oil, the average force and coefficient of friction decrease, while a good anti-friction effect is
observed.
