Abstract

In this work was explored the tribochemical system «bronze – organic additive – oil I-20A – steel» in terms of the formation of coordination compounds of copper (II) under mechanical activation of metal surfaces of friction pair and or-ganic additives. It was found that lubricant compositions contained organic solvents with high donor value DNSbCl5, in fric-tion pair «bronze – steel» had the best anti-wear properties, which clearly points to the crucial role of donor activity of or-ganic aprotic solvents during oxidation of metals. Herewith the decisive influence of donor activity of organic solvents as a part of lubricating compositions on wear remained unchanged regardless of the contact pressure in the studied friction pair, and a significant improvement of tribotechnical performance of lubricant compositions contained organic additives compared to «pure» oil I-20A depended on the electron-donor (DNSbCl5) and adsorption (Ir) activity of the studied organic additives. Key words: organic additives, tribochemical system, coordination compounds of copper (II), electron-donor activity, adsorption activity.
