A method for estimating the coefficient of friction at high temperatures up to 220°C in the thermal chamber of a bursting machine has been developed. It is shown that the coefficient of kinetic friction with a change in temperature from 25°C to 220°C varies from 0.04 to 0.1. In the developed method, the coefficient of static friction and the coefficient of kinetic friction are determined. The coefficient of static friction at a temperature of 25°C to 220°C varies from 0.06 to 0.13.
