FIELD: machine building.SUBSTANCE: antifriction composition is placed between friction surfaces for their modification. Said composition consists of serpentine-bearing material and bulged vermiculite and hydrocarbon binder. Bulged vermiculite is modified by natural high-molecular polysaccharide, preferably, chitozane. Said serpentine-bearing material represents serpentinite. The mix of dispersed solid particles features the following ratio of components in wt %: serpentine-bearing material - 80-93, modified bulged vermiculite - 7-20. Antifriction composition is produced by mixing said components and binder in hydrodynamic cavitation dispersant to obtain disperse solid particle sized to smaller than 1 mcm. Antifriction composition is produced at friction of contacting surfaces in the form of cermet film containing oxides of aluminium, silicon and magnesium.EFFECT: higher stability and durability, longer life.4 cl, 8 dwg, 5 tbl |
