Определено, что для всех видов покрытий на поверхности магниевых и алюминиевых сплавов характерны одинаковые особенности структурообразования: наличие тонкого плотного внутреннего подслоя и более толстого с развитой пористостью наружного. Такое структурное состояние защитного покрытия не является гарантированной защитой объектов от эксплуатационных воздействий, учитывая области их преимущественного использования – авиа-, автомобиле-, приборостроение, строительство и т. п. Проанализировано влияние щелочных электролитов с изменяющимся химическим составом за счет добавок фторидов натрия или калия на структуру и свойства указанных сплавов, а также на уровень основных эксплуатационных характеристик слоев, формируемых в таких электролитах. На основании этого сделан вывод о возможности продления их ресурса в эксплуатационных условиях. Выявлено, что существующие приемы и способы управления процессом микродугового оксидирования алюминиевых и магниевых сплавов, в частности режимы обработки и мощность технологического оборудования, определяют характер структурообразования и изменение фазового состава формируемых покрытий.</p></abstract><trans-abstract xml:lang="en"><p>The paper studies regularities and mechanisms of structure and phase formation in the surface layers of magnesium alloys when they are processed by method of micro-arc oxidation [MAO]. It has been determined that the same specific features of structure formation, namely: existence of a thin dense inner sublayer and a thicker outer sublayer with developed porosity are common for all types of coatings on the surface of magnesium and aluminum alloys. Such structural state of a protective coating can not be considered as a guaranteed protection against operational impacts, taking into account the fields of their primary application that is aviation construction, automotive construction, instrumentation, building construction, etc. The paper has analyzed the effect of alkaline electrolytes with varying chemical composition due to additions of sodium fluoride or potassium on the structure and properties of these alloys as well as on the level of basic performance characteristics of the layers formed in such electrolytes. On the basis of the analysis a conclusion has been made that it is possible to extend their life-span under operational conditions. It has been revealed that the existing techniques and methods for process control of MAO aluminum and magnesium alloys, particularly processing modes and technological equipment capacity determine a nature of structure formation and changes in a phase composition of the formed coatings.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>микродуговое оксидирование</kwd><kwd>структурообразование</kwd><kwd>электролит</kwd><kwd>фториды</kwd></kwd-group><kwd-group xml:lang="en"><kwd>micro-arc oxidation</kwd><kwd>structure formation</kwd><kwd>electrolyte</kwd><kwd>fluorides</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Kazanski B.
