METHOD FOR REDUCING FRICTION FACTOR Russian patent published in 2017 - IPC C23C26/00 C10M125/10 

FIELD: chemistry.

SUBSTANCE: method for preparing the composition-modifier for the metal friction pairs involves the preparation of a powder mixture of the dispersed particles of antigorite Mg₆Si₄O₁₀(OH)₈ and lizardite Mg₃Si₂O₅(OH)₄ and mixing of the said powder mixture in the oil. The said powder mixture is further added to the particles of chrysotile Mg₆Si₄O₁₀(OH)₈ and alpha-boron nitride in the following ratio, wt %: 2-10 antigorite, lizardite 2-20, 15-40, chrysotile and boron alpha-nitride 20-50. For liquid oils, the fractions of antigorite, lizardite and chrysotile 100-200 nm, the fraction 200-300 nm of boron alpha-nitride are used . For lubricating oils, the fractions of antigorite, lizardite and chrysotile 200-400 nm and the fraction 200-300 nm of boron alpha-nitride are used.

EFFECT: increasing the period of the scheduled recovery operations, reducing the cost of the repair work and increasing the efficiency of the product by reducing the effects of abrasive, cavitation and abrasion-cavitation wear in the metal friction pairs.
