Abstract

The article presents the results of scientific research on the processes of operation of graphite plastic in a tribological unit. The effect of sliding speed and load on the intensity of wear and coefficient of friction of graphite plastic was determined, and mathematical models describing the tribotechnical behavior of graphite plastic depending on the load and sliding speed of the friction unit were developed. The research carried out in the paper made it possible to reveal the influence of the technological parameters of the operation process on the intensity of linear wear and the coefficient of friction of graphite plastic. The obtained mathematical dependencies make it possible to reliably predict the duration of the developed graphite plastic in tribological units of modern technology, which is important for ensuring the efficiency and reliability of machines and mechanisms.
