Abstract
The PUMA lubricant with the use of additives has been investigated. The principle of their interaction with rubbing
surfaces is analyzed in order to evaluate their effectiveness as antifriction agents and their infl uence on the structure of
layers. The effect of an organophosphate and organosulfi de additive on surface wear compared. The infrared analysis
revealed an increase in the concentration of iron in the spent lubricant and a decrease in the concentration of organic
base oil in the system. The infl uence of functional groups and surface wettability on the formation of protective fi lms during
friction, was revealed.
