alloys is the micro-arc oxidation method (MAO), which is currently used in various industries. However, to achieve the desired characteristics and properties of oxide coatings, a large number of experiments are required to determine an optimal oxidation mode, which makes the MAO method labor-intensive and resource-consuming. One of the ways to solve this problem is the search for an informative parameter or several parameters, the use of which during the oxidation process monitoring allows identifying a relationship between the MAO modes and the specified characteristics of oxide coatings. This paper studies the influence of the specified technological MAO modes (current density, oxidation time, amplitude of acoustic emission (AE) signals recorded during MAO) on the morphology and parameters of oxide coatings (thickness δ and surface roughness <italic>R<sub>a</sub></italic>) deposited on the D16AT aluminum alloy clad with pure aluminum. Multivariate planning of an experiment and the performed regression analysis allowed establishing a relationship between two oxidation factors (current density and oxidation time) and the parameters of the produced coatings. The authors proposed an additional factor, which is determined in the monitoring mode during the oxidation process as the time from the moment when the maximum or minimum of the acoustic emission (AE) amplitude recorded in the MAO process is reached until the end of the oxidation process. The study established that the introduction of an additional factor allows increasing significantly the reliability of the dependence between the coating parameters obtained experimentally and by the computational method based on the regression analysis. The authors note that when performing MAO, with the additional use of the MAO process monitoring by recording the AE amplitude, it is possible to achieve a high reliability between the calculated and actual values of the parameters of oxide coatings.</p></abstract><trans-abstract xml:lang="ru"><p>Эффективным способом защиты вентильных металлов и их сплавов является метод микродугового оксидирования (МДО), в настоящее время применяемый в различных отраслях. Однако для достижения желаемых характеристик и свойств оксидных покрытий требуется большое число экспериментов по определению оптимального режима оксидирования, что делает метод МДО трудоемким и ресурсозатратным. Одним из путей решения данной проблемы является поиск информативного параметра или нескольких параметров, использование которых при мониторинге процесса оксидирования позволит установить связь между режимами МДО и заданными характеристиками оксидных покрытий. В работе изучено влияние заданных технологических режимов МДО (плотности тока, времени оксидирования, регистрируемой в процессе МДО амплитуды сигналов акустической эмиссии (АЭ)) на морфологию и параметры оксидных покрытий (толщину δ и шероховатость поверхности <italic>R<sub>a</sub></italic>), наносимых на алюминиевый сплав Д16АТ, плакированный чистым алюминием. Многофакторное планирование эксперимента и проведенный регрессионный анализ позволили установить связь между двумя факторами оксидирования (плотностью тока и временем оксидирования) и параметрами получаемых покрытий. Предложен дополнительный фактор, определяемый в режиме мониторинга в процессе оксидирования как время от момента достижения максимума или минимума регистрируемой в процессе МДО амплитуды АЭ до окончания процесса оксидирования. Установлено, что введение дополнительного фактора позволяет существенно повысить достоверность зависимости между параметрами покрытий, получаемыми экспериментально и расчетным методом на основе регрессионного анализа. Отмечено, что при выполнении МДО высокая достоверность между расчетными и фактическими значениями параметров оксидных покрытий может быть достигнута при дополнительном мониторинге процесса МДО путем регистрации амплитуды АЭ. </p></trans-abstract><kwd-group xml:lang="en"><kwd>micro-arc oxidation</kwd><kwd>oxide coating</kwd><kwd>acoustic emission</kwd><kwd>multivariate analysis</kwd><kwd>surface morphology</kwd><kwd>aluminum alloy</kwd><kwd>D16AT alloy</kwd><kwd>valve group alloy</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>микродуговое оксидирование</kwd><kwd>оксидное покрытие</kwd><kwd>акустическая эмиссия</kwd><kwd>многофакторный анализ</kwd><kwd>морфология поверхности</kwd><kwd>алюминиевый сплав</kwd><kwd>Д16АТ</kwd><kwd>сплавы вентильной группы</kwd></kwd-group><funding-group><funding-statement xml:lang="en">The work was supported by the Presidential grant for government support of leading scientific schools of the Russian Federation (project NSh-452.2022.4).</funding-statement><funding-statement xml:lang="ru">Работа выполнена при поддержке гранта Президента РФ для государственной поддержки ведущих научных школ Российской Федерации (проект НШ-452.2022.4).</funding-statement></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Yerokhin A., Nie X., Leyland A., Matthews A., Dowey S.
