Developing criteria for the rational selection of metal co-deposition conditions in an electrochemical cell with consumable anodes helps solve the problem of controlled alloy electrodeposition. In this work, an approach based on comparison of equilibrium potentials for two metal ion/metal pairs (A<sup>n+</sup>/A and B<sup>m+</sup>/B) is proposed to find the initial electrolysis parameters (concentration ratio and operating temperature). Theoretical analysis indicates the existence of regions of thermodynamic equilibrium for A<sup>n+</sup>/A and B<sup>m+</sup>/B pairs in the melt-solvent with a certain ratio of the A<sup>n+</sup> and B<sup>m+</sup> ion concentrations. Experimental and calculated values of equilibrium potentials for a wide range of metals in a melt based on an equimolar NaCl-KCl mixture containing 1 mol.% of depositing ions at 1000 K are compared. Venn-Euler diagrams are constructed for the pairs Ni<sup>2+</sup>/Ni, Mo<sup>3+</sup>/Mo, Cr<sup>2+</sup>/Cr, Pd<sup>2+</sup>/Pd, Rh<sup>3+</sup>/Rh, Ru<sup>3+</sup>/Ru and Ir<sup>3+</sup>/Ir in the temperature range from 948 to 1123 K and ion concentrations in the melt from 0.1 to 2 mol.%. The equilibrium regions in the Ni<sup>2+</sup>/Ni and Mo<sup>3+</sup>/Mo, Pd<sup>2+</sup>/Pd and Rh<sup>3+</sup>/Rh, Ru<sup>3+</sup>/Ru and Ir<sup>3+</sup>/Ir systems are calculated. It is shown that as the temperature decreases, the equilibrium regions expand for the studied pairs of noble metals, but narrow for nickel and molybdenum. The practical application of this method for a specific system requires taking into account additional data on the liquidus temperature and the vapor pressure of the melt to limit the equilibrium region on the left and right, respectively.</p></abstract><trans-abstract xml:lang="ru"><p>Получение сплавов электролизом расплавленных солей является важной научно-технической задачей. Разработка критериев рационального выбора условий соосаждения металлов в электрохимической ячейке с растворимыми анодами способствует решению задачи управляемого электроосаждения сплавов. В настоящей работе предложен подход, основанный на сравнении равновесных потенциалов для двух пар ион металла/металл (A<sup>n+</sup>/A и B<sup>m+</sup>/B) для нахождения исходных параметров электролиза (соотношения концентраций и рабочей температуры). Теоретический анализ указывает на существование областей термодинамического равновесия для пар A<sup>n+</sup>/A и B<sup>m+</sup>/B в расплаве-растворителе при определенном соотношении концентраций ионов A<sup>n+</sup> и B<sup>m+</sup>. Проведено сравнение экспериментальных и расчетных значений равновесных потенциалов для широкого круга металлов в расплаве на основе эквимольной смеси NaCl–KCl, содержащем 1 мол.% осаждаемых ионов, при 1000 K. Построены диаграммы Венна—Эйлера для пар Ni<sup>2+</sup>/Ni, Mo<sup>3+</sup>/Mo, Cr<sup>2+</sup>/Cr, Pd<sup>2+</sup>/Pd, Rh<sup>3+</sup>/Rh, Ru<sup>3+</sup>/Ru и Ir<sup>3+</sup>/Ir в интервале температур от 948 до 1123 K и концентраций ионов в расплаве от 0.1 до 2 мол.%. Рассчитаны области равновесия в системах Ni<sup>2+</sup>/Ni и Mo<sup>3+</sup>/Mo, Pd<sup>2+</sup>/Pd и Rh<sup>3+</sup>/Rh, Ru<sup>3+</sup>/Ru и Ir<sup>3+</sup>/Ir. Показано, что при понижении температуры области равновесия расширяются для исследованных пар благородных металлов, но сужаются для никеля и молибдена. Практическое применение данного метода для конкретной системы требует учета дополнительных данных о температуре ликвидуса и давлении пара расплава для ограничения области равновесия слева и справа соответственно.</p></trans-abstract><kwd-group xml:lang="en"><kwd>electrodeposition</kwd><kwd>molten salts</kwd><kwd>equilibrium potential</kwd><kwd>metals</kwd><kwd>alloys</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>электроосаждение</kwd><kwd>расплавленные соли</kwd><kwd>равновесный потенциал</kwd><kwd>металлы</kwd><kwd>сплавы</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Барабошкин А.Н.
