Abstract

Tribotechnical characteristics of samples produced from superhard boron nitride materials are studied during their friction on hard VK and TK alloys without lubricating fluids. The hard alloys show 3 to 6 times higher wear than boron nitride materials in all friction pairs with different combinations of materials. The maximum wear resistance is exhibited by friction pairs “composite 10–hard alloy”. The friction coefficient for all pairs of materials decreases with higher sliding speed, and temperature in the friction area increases. The maximum temperature in the friction area at which the materials can perform for a long time is 300 °С.
