Abstract
Compact ceramic electrode materials based on the Ti‒B‒Fe system modified with nanosized particles of aluminum nitride (up to 15 wt. %) were obtained by SHS extrusion. The effect of additives on the combustion characteristics of the studied system, as well as on the structure and phase composition of the obtained materials, is studied. The addition of aluminum nitride increases the content of boride and nitride phases in the final product. It was found that the introduction of modifying nanosized particles of aluminum nitride into the initial charge leads to the grinding of grains of boride and nitride phases, which together increases the microhardness by 10 %, in comparison with unmodified samples.
