Определены константы равновесия реакций взаимодействия хрома и кислорода, коэффициенты активности при бесконечном разбавлении и параметры взаимодействия в расплавах различного состава при 1873 К. Рассчитаны зависимости растворимости кислорода в изученных расплавах от содержания кобальта и хрома. По мере увеличения содержания кобальта в расплаве раскислительная способность хрома незначительно снижается. Кривые растворимости кислорода в никель-кобальтовых расплавах, содержащих хром, проходят через минимум, положение которого смещается в сторону более высоких содержаний хрома по мере увеличения содержания кобальта в расплаве.</p></abstract><trans-abstract xml:lang="en"><p>Thermodynamic analysis of oxygen solutions in nickel alloys containing cobalt and chromium was carried out. The equilibrium constants of interaction of chromium and oxygen, their activity coefficients at infinite dilution and the interaction parameters for melts of different composition at 1873 K were determined. The dependences of oxygen solubility on the contents of cobalt and chromium in the studied melts were calculated. The deoxidation ability of chromium slightly decreases with increasing cobalt content in melt. The oxygen solubility curves in the Ni – Co melts contai ning chromium pass through a minimum whose position shifts to the higher chromium concentrations with an increase in the cobalt content in the melt.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>никелевые сплавы</kwd><kwd>кобальт</kwd><kwd>хром</kwd><kwd>кислород</kwd><kwd>термодинамический анализ</kwd></kwd-group><kwd-group xml:lang="en"><kwd>nickel alloys</kwd><kwd>cobalt</kwd><kwd>chromium</kwd><kwd>oxygen</kwd><kwd>thermodynamic analysis</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">РФФИ</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">Логунов А.В., Шмотин Ю.А.
