IMPROVEMENT OF TRIBOLOGICAL PROPERTIES FOR LUBRICANTS BY ADDING GRAPHENE CONCENTRATE

Abstract

This work is improving the performance properties of greases additives graphene concentrate. It has been established that the addition of 1% graphene concentrate to the lubricant Solidol J contributes to an increase in its anti-wear properties by more than 30 percent. With the enrichment of commercial grease Lithol-24 with graphene concentrate, a decrease in the diameter of the spot of wear of the balls was determined at the plate size from 0.36 mm to 0.30 mm. As a result of testing lubricants in rolling bearings, a decrease in the heating temperature of bearings operating on lubricants enriched with graphene concentrate was found in comparison with commercial lubricants.
