Abstract

In this work the constructive solution of the friction node is proposed, which provides the possibility to obtain reliable information about the tribological characteristics of the materials for work in heavy loaded slip supports. The method of determining the expediency of application in friction pairs of different materials is considered, which is based on certain shapes and sizes of the contact spot and the state of the friction track on the counter bodies. The efficiency of polycrystalline superhard materials application based on the wurtzite boron nitride in heavy loaded friction pairs due to an increase in the antifriction characteristics of the pair by the formation of graphitelike boron nitride on the surface of a thin film В2О2 as a result of the reverse phase transformation of dense phases (cBN + wBN) → gBN is shown.
