Experimental results on tribological characteristics of the friction elements in the presence of lithium- based lubricants including copper carboxylates of various structures are presented. It is established that introducing of the studied copper carboxylates into lithium grease reduces the friction coefficient by 2,7–5,11 times, and the wear of friction elements by 1,35–2,11 times. It is found that the copper carboxylates in which hydrocarbon radicals are elongated in trans-conformation used as antifriction and anti-wear additives to lithium based greases are more effective than carboxylates with branched structure. The data obtained will allow to simulate and synthesize more effective anti-friction and anti-wear additives based on copper carboxylates.

Keywords: tribology, copper carboxylates, copper valerate, copper isovalerate, friction coefficient, wear, lubricant, liquid crystals
