При синтезе из Cr:Al:TiC:C преобладает МАХ-фаза 312 (Cr2/3Ti1/3)3AlC2, а при синтезе из Cr:Al:Ti:C — МАХ-фаза 211 Cr1.5Ti0.5AlC. В качестве примесей в образцах присутствуют á-Al2O3, карбиды и оксиды хрома. Сочетание методов рентгеновской дифракции и рентгеновской фотоэлектронной спектроскопии позволило выявить существенные различия в химическом и фазовом составах поверхности и объема образцов. Установлено, что оксиды алюминия и хрома, а также карбид Cr7C3 формируются на поверхности МАХ-фаз в процессе синтеза, подобно тому, как это происходит при термическом окислении Cr2AlC и формировании на поверхности защитного слоя из á-Al2O3/Cr7C3. Образование защитного слоя имеет важное значение для получения материала на основе Cr–Ti–Al–C с высокой термохимической стабильностью в агрессивных средах.</p></abstract><trans-abstract xml:lang="en"><p>Using vacuum sintering at 1300ºC of Cr, Al, graphite, and TiC or Ti powders, we obtained products consisting of two MAX phases: 312 and 211, the predominant formation of which depends on the type of precursor – TiC or Ti. In the synthesis from Cr:Al:TiC:C, the MAX phase 312 (Cr2/3Ti1/3)3AlC2 predominates, while in the synthesis from Cr:Al:Ti:C, the MAX phase 211 Cr1.5Ti0.5AlC predominates. α-Al2O3, carbides, and chromium oxides are present in the samples as impurities. A combination of X-ray diffraction and X-ray photoelectron spectroscopy methods made it possible to reveal significant differences in the chemical and phase composition of the surface and bulk of the samples. It was established that aluminum and chromium oxides, as well as Cr7C3 carbide, are formed on the surface of MAX phases during synthesis, similar to what occurs during the thermal oxidation of Cr2AlC and the formation of a protective layer of α-Al2O3/Cr7C3 on the surface. Formation of the protective layer is essential for producing Cr–Ti–Al–C-based materials with high thermochemical stability in aggressive environments.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Ti–Cr–Al–N</kwd><kwd>(Cr2/3Ti1/3)3 AlC МАХ-фаза</kwd><kwd>Cr1.5Ti0.5 AlC МАХ-фаза</kwd><kwd>рентгеновская дифракция</kwd><kwd>рентгеновская фотоэлектронная спектроскопия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Ti–Cr–Al–N</kwd><kwd>(Cr 2/3Ti1/3 )3 AlC2 MAX phase</kwd><kwd>Cr1.5Ti0.5 AlC MAX phase</kwd><kwd>X-ray diffraction</kwd><kwd>X-ray photoelectron spectroscopy</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках совместного белорусско-российского проекта, финансируемого Белорусским фондом фундаментальных исследований (грант № Т23РНФМ-35) (Беларусь) и Российским научным фондом (грант № 24-49-10012) (Россия).</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">L.
