TRIBOTECHNICAL LUBRICANT AND LUBRICATING COMPOUND Russian patent published in 2008 - IPC C10M103/02 C10M125/02 

FIELD: lubricating materials.

SUBSTANCE: lubricant contains X-ray amorphous carbon which has the following characteristics: particle size of 30-50 nm from tunnel electron microscopy; temperature at which oxidation starts in air - 300°C; concentration of non-conjugated double bonds, determined from reaction with a neutral solution of potassium permanganate - not less than 1 for 5 atoms of carbon; concentration of paramagnetic centres on the EPR signal with a g-factor of 2.022 - not less than 1 for 1200 atoms of carbon. The lubricating compound contains base oil and X-ray amorphous carbon.

EFFECT: lowering of the intensity of wearing out of the friction surface, increased sedimentation stability of the compound during storage.
