Influence of carbon materials on the structure and phase composition of composite ceramics based on a multicomponent system Hf–Ti–B–C–N

The paper considers the effect of carbon on composite ceramics based on the multicomponent Hf-Ti-B-C-N system. The process of obtaining a composite material is based on high-temperature exothermic reactions. In this case, the elements Ti and Hf are subjected to vacuum sintering to form a solid solution (Ti, Hf) and are used as the initial components of the Hf-Ti-B-C mixture. Chemical production waste (carbon black) and graphite are used as carbon. The structure and phase composition of composite ceramics based on the Hf-Ti-B-C-N system are studied depending on the allotropic modifications of carbon (carbon black, graphite). The presented results demonstrate the fundamental possibility of obtaining composite ceramics (Hf,Ti)CN-(TiB2/TiC-TiB2) using powder metallurgy methods. It is shown that the use of thermally coupled synthesis and graphite as a carbon source promotes the formation of the TiC phase in the composite structure.
