Conclusions During the production of the composite materials under consideration by orthodox sintering the cubic boron nitride and hard metal react with each other, with the formation of borides and appearance of porosity as a result of the evolution of gaseous reaction products, and the strength of the materials is therefore low. During hot pressing the reaction between the components of the CBN-containing materials is less intense because the sintering temperature is lower and the holding time shorter, but the strength of the resultant materials remains comparatively low. The most promising method of obtaining composite CBN-containing materials exhibiting high abrasive ability in the grinding of hard and brittle materials is shock sintering.
