Одним из способов их защиты являются покрытия, полученные методом химического оксидирования в молибдатных составах. Для увеличения противокоррозионных свойств таких покрытий используется введение модифицирующих добавок в конвертирующий состав и последующее наполнение покрытий в растворе ингибитора коррозии. В настоящей работе были исследованы молибдатные покрытия, модифицированные комбинациями добавок: силикатом натрия и тетраборатом натрия, нитратом магния и карбонатом натрия. Было показано, что первая комбинация добавок позволяет получать более стабильные покрытия, с точки зрения защитных свойств, при изменении температуры конвертирующего состава, при вариации времени оксидирования и при многократном оксидировании в одном растворе.</p></abstract><trans-abstract xml:lang="en"><p>The presence of corrosive agents, such as chlorides, in the atmosphere or water can lead to active pitting corrosion of magnesium-containing aluminum alloys, which include AMg3 alloy. One of the ways to protect them are coatings obtained by chemical oxidation in molybdenum compounds. To increase the anticorrosive properties of such coatings, the introduction of modifying additives into the converting composition and subsequent filling of coatings in a solution of a corrosion inhibitor is used. In this work, we studied the molybdenum coatings modified with combinations of additives: sodium silicate and sodium tetraborate, magnesium nitrate and sodium carbonate. It has been shown that the first combination of additives makes it possible to obtain more stable coatings in terms of protective properties when the temperature of the converting compound changes, the oxidation time varies, and multiple oxidation in a solution.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>алюминиевые сплавы</kwd><kwd>конверсионные покрытия</kwd><kwd>химическое оксидирование</kwd><kwd>питтинговая коррозия</kwd><kwd>ингибиторы коррозии</kwd><kwd>молибдаты</kwd></kwd-group><kwd-group xml:lang="en"><kwd>aluminum alloys</kwd><kwd>conversion coatings</kwd><kwd>chemical oxidation</kwd><kwd>pitting corrosion</kwd><kwd>corrosion inhibitors</kwd><kwd>molybdates</kwd><kwd>chromate-free technologies</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках Госзадания при финансовой поддержке Минобрнауки России.</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">Коррозия алюминия и алюминиевых сплавов, Под ред.
