Abstract

The present work is designed to provide understanding in the synthesis of ceramic-metal hard materials composites. The materials of interest are nitrides and carbides such as BN, TiC along with Fe, Cr, and Ni binder metals. This report deals with the structure and properties of cubic boron nitride (c-BN) based composites that were produced by self-propagating high-temperature synthesis (SHS). Scanning electron microscopy (SEM) technique was used to characterize the microstructure of material. Tribology properties of the composite have been tested in dry sliding conditions according to standard ASTM-B 611-85 and slurry hydroerosion in a sodium solution.
