ANTIFRICTION COMPOUND EMULSIFIED IN LUBRICATING MEDIA FOR ENGAGEABLE SURFACES Russian patent published in 1995 - IPC

FIELD: antifriction coatings. SUBSTANCE: antifriction compound emulsified in lubricating media consists of the following components, parts by mass: polyperfluoro-propylene oxide at content of fluorine ion of 0.003-0.005 mg/g of polymer and molecular mass of 2500-9000, 25-50; polyoxyethylene glycol at molecular mass of 400, 15-50; refined alkylaryl sulfonate based on sodium salts of petroleum sulfonates, 25-35 and fluorine chlorine carbon oil which is mixture of stabilized liquid polymers of trifluoroethylene chloride, 10-15. Comparative wear resistance of engageable steel surfaces coated with lubricating oil with this antifriction compound is 2.15 to 2.36 as compared with standard compound whose wear resistance is equal to 1.25 to 1.33. EFFECT: high wear resistance of coats. 2 tbl
