Increasing the antifriction of the friction pair by changing the structure of the friction surface

Studies have shown that the improvement of the antifriction properties of the friction surface of the Uglekon-T material paired with 40X13 steel was achieved by treating the surface of the Uglekon-T material in selenium and polytetrafluoroethylene vapors. The friction surface saturated with the Se-P...

Description
Summary:Studies have shown that the improvement of the antifriction properties of the friction surface of the Uglekon-T material paired with 40X13 steel was achieved by treating the surface of the Uglekon-T material in selenium and polytetrafluoroethylene vapors. The friction surface saturated with the Se-PTFE antifriction composition has a low friction coefficient up to a temperature of 500 °C, which is in the range of 0.07–0.12. At a load of 1.0 MPa, a sliding speed of 0.05 m/s and a temperature of 500 °C the friction coefficient of the treated surface is 4.88 times lower than that of the untreated surface. At a temperature of 500 °C and a load of 1.0 MPa in the velocity range of 0.05–0.02 m/s the change in the friction coefficient is insignificant and lies in the range of 0.07–0.11.
