Синтез порошков (B4C, CrB2 и Cr3C2) для спекания осуществлялся с использованием оригинального безвакуумного электродугового реактора постоянного тока при длительности обработки исходной смеси порошков воздействием дугового разряда 60 с и силе тока, установленной на источнике постоянного тока, 200 А. Спекание объемных образцов на основе карбида бора (B4C) и диборида хрома (CrB2) проводилось при одинаковых параметрах – температуре t = 1800 °С и давлении Р = 60 МПа, а спекание керамического образца на основе карбида хрома (Cr3C2) – при t = 1300 °С и Р = 30 МПа. Также в процессе спекания объемных образцов на основе карбида бора в ряде случаев применялись спекающие добавки – 25 мас. % Cr3C2 и 20 мас. % CrB2 . Посредст­вом рентгеновской дифрактометрии был изучен фазовый состав спеченных образцов. Микроструктуру и элементный состав полученных образцов определяли с помощью растровой электронной микроскопии. Твердость спеченной керамики оценивали с использованием твердомера с наконечником Виккерса при малой нагрузке в 1 кг – установлено, что твердость образца B4C составляет 22,7 ± 1,8 ГПа, CrB2 – 12,6 ± 0,3 ГПа, Cr3С2 – 11,4 ± 0,1 ГПа. Введение спекающей добавки в виде 25 мас. % Cr3С2 при получении керамики на основе B4C привело к снижению твердости до 17,7 ± 5,6 ГПа, однако наблюдалось повышение трещиностойкости полученного образца с 2,5 ± 0,2 до 3,3 ± 0,3 МПа·м1/2. Добавка 20 мас. % CrB2 при спекании B4C позволила увеличить твердость объемного образца с 22,7 ± 1,8 до 26,8 ± 1,3 ГПа.</p></abstract><trans-abstract xml:lang="en"><p>This study presents the results of spark plasma sintering of powders within the boron–carbon–chromium system, focusing on boron carbide (B4C), chromium carbide (Cr3C2 ), and chromium diboride (CrB2 ). The powders were synthesized using the original vacuum-free direct current arc reactor, where the starting powder mixture was exposed to an arc discharge for 60 s under a direct current of 200 A. Bulk samples based on B4C and CrB2 were sintered under identical conditions, with a temperature of 1800 °C and a pressure of 60 MPa, while the sintering of Cr3C2-based ceramics was conducted at 1300 °C and 30 MPa. In some cases, sintering additives – 25 wt. % Cr3C2 and 20 wt. % CrB2 – were introduced during the sintering of B4C-based bulk samples. The phase composition of the sintered samples was analyzed using X-ray diffraction (XRD), while the microstructure and elemental composition were examined via scanning electron microscopy (SEM). The hardness of the sintered ceramics was measured using a Vickers indenter under a load of 1 kg, revealing hardness values of 22.7 ± 1.8 GPa for B4C, 12.6 ± 0.3 GPa for CrB2 , and 11.4 ± 0.1 GPa for Cr3C2 . The introduction of 25 wt. % Cr3C2 as a sintering additive in B4C-based ceramics reduced the hardness to 17.7 ± 5.6 GPa; however, it significantly improved the fracture toughness, increasing it from 2.5 ± 0.2 to 3.3 ± 0.3 MPa·m1/2. Conversely, the addition of 20 wt. % CrB2 during B4C sintering led to an increase in the bulk sample’s hardness from 22.7 ± 1.8 GPa to 26.8 ± 1.3 GPa.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>композиционная керамика</kwd><kwd>B4C</kwd><kwd>CrB2</kwd><kwd>Cr3С2</kwd><kwd>безвакуумный электродуговой метод</kwd><kwd>искровое плазменное спекание</kwd><kwd>твердость</kwd></kwd-group><kwd-group xml:lang="en"><kwd>composite ceramics</kwd><kwd>B4C</kwd><kwd>CrB2</kwd><kwd>Cr3С2</kwd><kwd>vacuum-free arc discharge method</kwd><kwd>spark plasma synthesis</kwd><kwd>hardness</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при финансовой поддержке Министерства науки и высшего образования Российской Федерации (проект № FSWW-2023-0011).</funding-statement><funding-statement xml:lang="en">This work was supported by the Ministry of Science and Higher Education of the Russian Federation (Project No. FSWW-2023-0011).</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Domnich V., Reynaud S., Haber R.A., Chhowalla M.
