Abstract
Abstract—This paper is devoted to determining the kinetic regularities of the formation of surface antifriction films in refined sunflower oil. IR ATR spectroscopy revealed that the main chemical reactions leading to antifriction film formation occur on the friction surface in the first 20 s after the start of tribological tests. It was established experimentally that the C=C bonds of fat molecules do not participate in the formation of the antifriction film. The main changes in the IR spectra of the antifriction film compared to the original oil are a decrease in the intensity of C=O bond vibrations and an increase in the intensity of C–H bond vibrations. This indicates that the film is not a product of oxidation and subsequent drying of the oil.
