В работе проведено исследование возможности Al2O3 и Al:Zn (1:1) играть роль защитных покрытий для ВЭС РЗМ GdTbDyHoSc и GdTbDyHoY. Образцы ВЭС РЗМ синтезированы из металлов чистотой ≥99,9 % расплавлением в электродуговой печи в атмосфере Ar (99,99 %). Покрытия на образцы наносились методом сверхзвукового плазменного напыления. Коррозионную стойкость определяли в камере соляного тумана в течение 48 ч. Установлено, что для всех исследованных образцов коррозионное воздействие в условиях соляного тумана приводит к деградации основного материала сплава. Образцы с покрытием Al:Zn (1:1) в условиях соляного тумана показывают меньшую стойкость, чем образцы с покрытием из Al2O3 вследствие имеющего место химического взаимодействия между алюминием и раствором хлорида натрия.</p></abstract><trans-abstract xml:lang="en"><p>Nowadays high-entropy alloys (HEAs) with a hexagonal close packed structure consisting of rare-earth metals (REM) are of particular interest. In this work, we investigated the possibility of using of Al2O3 and Al:Zn (1:1) as a  protective coatings for REM HEAs GdTbDyHoSc and GdTbDyHoY. The REM HEAs samples were synthesized from metals of purity ≥99.9 % by melting in an electric arc furnace under Ar atmosphere (99.99 %). The samples were coated by supersonic plasma spraying. Corrosion resistance was determined in a salt mist chamber for 48 h. It was found that for all studied samples corrosive effect in conditions of salt mist leads to degradation of the base material of the alloy. Samples coated with Al:Zn (1:1) under salt mist conditions showed less resistance than samples coated with Al2O3 due to the chemical interaction between aluminum and sodium chloride solution. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>коррозия</kwd><kwd>защитные покрытия</kwd><kwd>коррозионная стойкость</kwd><kwd>ограничение применения</kwd><kwd>ВЭС</kwd><kwd>РЗМ</kwd></kwd-group><kwd-group xml:lang="en"><kwd>corrosion</kwd><kwd>protective coatings</kwd><kwd>corrosion resistance</kwd><kwd>limitation of use</kwd><kwd>high-entropy alloy (HEA)</kwd><kwd>rare-earth metal (REM)</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при поддержке Российского научного фонда (грант № 21-43-00015) с использованием оборудования ЦКП «Урал-М».</funding-statement><funding-statement xml:lang="en">The work was supported by the Russian Science Foundation (grant No. 21-43-00015) using the equipment of the Center for Collective Use “Ural-M”.</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">Zhang Y., Zuo T.T., Tang Z., Gao M.C., Dahmen K.A., Liaw P.K., Lu Z.P.
