Abstract
This paper presents the results of a study of different types of counterbodies on the tribological properties of polytetrafluoroethylene (PTFE). The characteristics of the polymer, the roughness and hardness of counterbodies made of the following materials are given: copper, aluminum, brass and steel grade 45. It is shown that the best wear resistance is obtained for a friction pair – polytetrafluoroethylene with steel grade 45 and brass. The friction surfaces of the counterbodies and the polymer were studied by optical, electron microscopy, and IR spectroscopy.
