Замещение было инициировано путем добавления в состав сернокислого раствора – электролита сульфатов кобальта или никеля, что позволило получить пленки с тетрагональным типом кристаллической решетки, характерной для фазы CuBi2 O4 . При этом анализ структурных параметров и изменений элементного состава пленок показал, что добавление в состав электролита сульфатов никеля и кобальта приводит к формированию тетрагональной фазы по типу замещения, связанному с частичным замещением меди никелем или кобальтом в зависимости от состава раствора – электролита. В ходе моделирования процессов деградации пленок при внешних воздействиях были получены результаты коррозионных испытаний CuBi2 O4 пленок в агрессивной среде модельного раствора 0.1 M NaCl при различных температурах среды. Определены зависимости изменения степени структурного упорядочения и степени разупрочнения исследуемых пленок в зависимости от времени нахождения в агрессивной среде. Установлено, что замещение меди кобальтом или никелем приводит к увеличению сопротивляемости исследуемых пленок к деградации и окислению, что свидетельствует о положительном эффекте замещения, обуславливающему снижение скорости деградации поверхности пленок при контакте с агрессивной средой.</p></abstract><trans-abstract xml:lang="en"><p>The work examines the effect of substitution of copper with cobalt and nickel in the composition of CuBi2 O4 films obtained using the electrochemical deposition method. The substitution was initiated by addition of cobalt or nickel sulfates to the sulfuric acid electrolyte solution, which made it possible to obtain films with a tetragonal type of crystal lattice characteristic of the CuBi2 O4 phase. Moreover, an analysis of the structural parameters and changes in the elemental composition of the films showed that the addition of nickel and cobalt sulfates to the electrolyte leads to the formation of a tetragonal phase according to the type of substitution associated with the partial replacement of copper by nickel or cobalt, depending on the composition of the electrolyte solution. During simulation of the film degradation processes under external influences, the results of corrosion tests of CuBi2 O4 films in the aggressive environment of a model solution of 0.1 M NaCl at different ambient temperatures were obtained. The dependences of changes in the structural ordering degree and the softening degree of the films under study were determined depending on the time spent in an aggressive environment. The substitution of copper with cobalt or nickel has been found to increase the resistance of the studied films to degradation and oxidation, indicating a positive substitution effect, reducing the degradation rate of the surface of the films in contact with the aggressive medium.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>тонкие пленки</kwd><kwd>электрохимический синтез</kwd><kwd>антикоррозионные покрытия</kwd><kwd>CuBi2 O4</kwd><kwd>структурное разупорядочение</kwd></kwd-group><kwd-group xml:lang="en"><kwd>thin films</kwd><kwd>electrochemical synthesis</kwd><kwd>anti-corrosion coatings</kwd><kwd>CuBi2 O4</kwd><kwd>structural disorder</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Исследование выполнено в рамках грантового финансирования при поддержке МНВО  РК AP14871152 «Синтез CuBi/CuBi2 O4  пленок – перспективных материалов для создания защитных покрытий от электромагнитного и ионизирующего излучения».</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">Choi Y.J. et al.
