Keywords: Geo-modifier of friction, Plastic lubricant, Serpentine, Wea

Abstract: The article describes the influence of friction geo-modifier on the antiwear properties of greases and gear oils. Geo-modifiers of friction are the fine powders of mineral materials. This work is directed on the investigation of the influence of geo-modifiers of friction in the form of hard lubricant compositions, based on a mineral serpentine, on the anti-wear properties of plastic lubricants. This composition is the fine powder serpentine with the addition of components such as chalk, borax, kaolin and talc. We compared the antiwear properties of the greases without geo-modifiers of friction and the antiwear properties of greases containing the geomodifiers of friction from 1 to 3%. The Litol-24, Shell Gadus S3, Mobilgrease XHP 222, Castrol LMX greases were used for testing. The four-ball machine of friction was used for tests. As geo-modifier the serpentine was used, the fraction of which has a size from 0.87 to 2.2 µm. The parameter as the wear scar diameter was used for evalu..
