ABSTRACT:
The present invention relates to the machine building industry and it is used for coating of friction surfaces by triboceramics to decrease wear and to reduce the friction coefficient. The triboceramic compound contains oxides—magnesium oxide MgO, silica SiO2, alumine Al2O3, calcium oxide CaO, ferric oxide Fe2O3, being in the chemical composition of serpentine and talc, the natural and/or synthesized heat unprocessed and/or dehydrated minerals—serpentine, talc, clinochlore, magnesite, quartz and aluminium hydroxide are introduced forming a mixture with the following composition of oxides, in mass %: SiO2-46-54; MgO-26-32, Al2O3-2-5; Fe2O3-1.0-1.5; CaO-0.1-0.3, water H2O-5 or less.
