Summary:In the article considered the problem of the devastating impact of friction to the machine parts’ and mechanisms, and ways to solve this problem. Described the method of mechanical activation of the graphite grease in a planetary mill. Experimentally determined friction coefficients of sliding of standard and mechanically activated of the graphite grease. Established that as a result of mechanical activation friction coefficient of sliding decreases in the 2.2–2.5 times. The obtained spectra of Raman scattering allow to assume, that the reduction in the friction coefficient of sliding happens at the expense of forming in a graphite grease of graphene nanostructures.
