Покрытия Ni-Cr-Al, широко используемые в аэрокосмической, автомобильной и энергетической отраслях, ценятся за их исключительную твёрдость, износостойкость и стабильность при высоких температурах. Градиентные покрытия, созданные путём настройки параметров детонационного напыления, имеют микроструктуру, которая сочетает твёрдую износостойкую поверхность с мягким пластичным подслоем, что улучшает их способность выдерживать нагрузки и трибологические свойства. Экспериментальные результаты показывают, что градиентные покрытия достигают более низких и стабильных коэффициентов трения (0,3-0,4) по сравнению с однородными покрытиями (0,4-0,5). Эти результаты подчеркивают превосходную износостойкость и долговечность градиентных покрытий Ni-Cr-Al, что делает их особенно подходящими для применения в условиях длительной эксплуатации. Данное исследование способствует разработке усовершенствованных систем покрытий, оптимизированных для работы в экстремальных условиях.</p></abstract><trans-abstract xml:lang="en"><p>This study explores the tribological properties of Ni-Cr-Al coatings applied through detonation spraying technology, with a focus on the comparison between gradient coatings and homogeneous coatings. Ni-Cr-Al coatings, widely used in aerospace, automotive, and energy industries like power plants, are valued for their exceptional hardness, wear resistance, and high-temperature stability. Gradient coatings, produced by tailoring the detonation spraying parameters, exhibit a microstructure combining a hard, wear-resistant surface with a softer, ductile subsurface, enhancing their load-bearing capacity and tribological performance. Experimental results reveal that gradient coatings achieve lower and more stable friction coefficients (0.3-0.4) compared to homogeneous coatings (0,4-0,5), attributed to their optimized stress distribution and reduced adhesive interactions. These findings underscore the superior wear resistance and durability of gradient Ni-Cr-Al coatings, making them highly suitable for applications involving prolonged operation under sliding conditions. This research contributes to the development of advanced coating systems optimized for demanding operational environments.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>детонационное напыление</kwd><kwd>покрытия Ni-Cr-Al</kwd><kwd>градиентные покрытия</kwd><kwd>однородные покрытия</kwd><kwd>трибологические свойства</kwd></kwd-group><kwd-group xml:lang="en"><kwd>detonation spraying</kwd><kwd>Ni-Cr-Al coatings</kwd><kwd>gradient coatings</kwd><kwd>homogeneous coatings</kwd><kwd>tribological properties</kwd></kwd-group><funding-group xml:lang="en"><funding-statement>This research has been funded by the Committee of Science of the Ministry of Science and Higher Education of the Republic of Kazakhstan (Grant No. BR24992876)</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">Room- and high temperature wear resistance of MCrAlY coatings deposited by detonation gun (D-gun) and supersonic plasma spraying (SSPS) techniques / М.
