Abstract
The article studied the issues of friction of a carbon-containing material with 40X13 steel at high temperatures in a carbon dioxide environment for use in friction units operating in the atmosphere of Venus. The influence of the sliding speed and the contact load is investigated. It is experimentally shown that the test environment in the form of carbon dioxide has a positive effect on the coefficient of friction in the direction of its reduction. At a temperature of 400…500 ° C, a load of 0.67 MPa and a speed of 0.05 m/s, the coefficient of friction is in the range of 0.13-0.19.
