ANTIFRICTION ADDITIVE Russian patent published in 2004 - IPC

FIELD: antifriction materials. SUBSTANCE: antifriction additive for use in motor car, tractor, ship, and aircraft engines as well as for increasing life time of working machines in processing areas is based on lubricating oil and contains 0.1 to 0.5% solid modifier, namely superfine graphite-diamond blend powder. The latter is characterized by primary particle size 4-6 nm, specific surface area 400-500 sq.m/g, and proportion of diamond in graphite-diamond blend at least 30%. EFFECT: reduced running-in time for engines, increased sedimentation stability of additive, and reduced toxicity of exhaust gases.
