Аннотация:The tribotechnical characteristics of polymer composites based on PTFE and layer silicates (serpentinite) were studied, depending onthe test duration time. It was indicated that adding a serpentinite and magnesium spinel increased the wear resistance of the compositeby up to 480 times compared to the original PTFE. It was found that particles of fillers and PTFE promote formation of a secondarystructure on the friction surface, helping reduce the material wear process. The method of infrared (IR) spectroscopy and EDS showedthat tribochemical reactions take place on the friction surface of composites.*** Keywords: polytetrafluoroethylene, composite, layered silicates, serpentinite, magnesium spinel, friction surface, tribochemical processes
