ANTIFRICTION MODIFYING COMPOSITION FOR TREATMENT OF SOLID SURFACE Russian patent published in 1998 - IPC

FIELD: production of high strength antiwear modifying coating on metal surfaces of machine and units being brought into contact. SUBSTANCE: antifriction composition comprises, mas.%; perfluoroorganic compound, 1.0-2.0; calcium and/or barium alkyl arylsulfonate as dispersing agent, 1.0-10.0; mineral oil, 79.0-89.0. Distillation fraction of oxidation of hexafluoropropylene being isolated at 3 mm Hg and at temperature higher 180 C which comprises product having common formula with molecular weight 3000-5000 where , n=3-100, m= 0-100, k= 0-100; or distillation fraction of product of low temperature catalytic polymerization of hexafluoropropylene oxide having common formula with molecular weight 3000-6000 where n= 10-40, is used as mentioned above perfluoroorganic compound. EFFECT: improved antifriction ability, decreased friction index. 2 tbl
