Abstract

A study of the tribological properties of superhard materials (SHM) based on cubic boron nitride (cBN) and nitride ceramics for dry friction in the air for hard metals was conducted. It is found that at a constant load (100 N) and slip velocity increasing (1—6 m/s) the friction factor is reduced and the temperature in the friction zone increases. It is shown that wear resistance of couples cemented carbide — materials based on cBN increases in the following sequence: composite 05-ИТ – elbor-P — hexanit-P. Maximum wear resistance has hexanit-P — biphase composite material: 60% BNсф, 40% BNв.
