Abstract <p>The problem of developing energy-efficient methods for producing ultra-high-temperature ceramic materials based on HfB₂(ZrB₂)–SiC is highly relevant and has practical significance, as these materials are considered extremely promising for use in aerospace, high-temperature thermal insulation, and certain other applications. The study investigated the effect of adding 5 and 15 vol % Ti₂AlC on the consolidation process of a ceramic composite by hot pressing at temperatures of 1600–1800°C. It was shown that an increase in the consolidation temperature and the content of the Ti₂AlC MAX phase in the initial powder composition leads to a significant increase in the amount of dissolved titanium in the hexagonal HfB₂ phase (from ~0.13 for a sintering temperature of 1600°C and an addition of 5 vol % Ti₂AlC to ~0.3 for a temperature of 1800°C and an addition of 15 vol % Ti₂AlC), as well as to an increase in the content of the (Hf,Ti)(B,C) phase in the resulting composites. The microstructure and distribution of elements in the resulting composite materials were studied using SEM and AFM. KPFM also confirmed the conclusions about the increase in the fullness of the interaction between HfB₂ and the MAX phase with an increase in the consolidation temperature. The similarity of the oxidation mechanisms of ceramics with close density values (66 and 74%) is noted.</p>
