Abstract
The results of high-temperature tribological research of carboncarbon material at friction on heat-resistant stainless steel 40Х13 in the temperature range from +20 to +700 °С are presented. Friction surface modifiers change the structure of the friction surface of carbon-carbon material CCCM-2D, improve its antifriction properties, and reduce the friction coefficient. The structurally modified friction surface provided by modifiers PTFE, SnSe-PTFE, and InSb-Se-PTFE achieves friction coefficient values of 0.08 to 0.15 in the temperature range of +300 to +500 °C. These results are intended for use in the creation of sliding bearings for operation at high temperature, as they show that structurally modified friction surfaces of carbon-carbon material can withstand high temperatures without losing their friction-reducing abilities.
