Структура та властивості полікристалів, одержаних при спіканні порошків сBN з добавками ZrN і Al в умовах високого тиску

Abstract

The experimental samples of superhard polycrystals was received in cBN-ZrN-Al system by sintering powders at high pressure and temperature (7,7 GPa, 2300 K). Influence of zirconium nitride quantity on structure, hardness, density, abrasive wear of the received polycrystals is studied.
