Abstract
Compact ceramic materials based on the Ti‒B system modified with 5 wt. % of nanosized Si3N4 particles. The results of studies of the structure, phase composition, and physical and mechanical characteristics of the materials obtained are presented. It is shown that the addition of Si3N4 promotes the formation of new phases, in particular, titanium diboride and nitride in the final product. It was found that the introduction of modifying nanosized Si3N4 particles into the initial charge leads to an increase in hardness and microhardness by 15‒20 %, as well as to an increase in crack resistance by 1,5 times in comparison with unmodified samples.
