Resumo

Tests for the wear of polytetrafluoroethylene and composites on its basis with different glass transition and softening temperatures has been performed. It has been demonstrated that a rise in temperature leads to an abrupt rise in wear due to the build up of adhesive on the metallic counterbody. The method of temperature calculations in the frictional contact zone has been developed and tested. It has been demonstrated that the introduction of filler into polytetrafluoroethylene results in a rise in the glass transition temperature from–120°C, which corresponds to polytetrafluoroethylene, to +150°C.
