Поэтому для их защиты используются различные покрытия, в том числе, полученные методом химического оксидирования. В данной работе были проведены исследования бесхроматных ингибированных конверсионных покрытий ИФХАНАЛ-3 в камере влажности Г-4 в сочетании со спектроскопией электрохимического импеданса, кондуктометрией и рентгеноспектральным микроанализом. Это позволило выявить факторы начала коррозионного процесса и, в частности, показать отсутствие десорбции ингибитора коррозии в процессе испытаний. При этом было показано, что введение в конвертирующий состав 1,2,3-бензотриазола способствуют как увеличению активного сопротивления (Rf) оксидной плёнки, так и более позднему появлению первых коррозионных поражений на покрытии в сравнении с немодифицированными покрытиями. С помощью метода кондуктометрии было показано, что в процессе испытаний в камере влажности наблюдается снижение пористости покрытий.</p></abstract><trans-abstract xml:lang="en"><p>Aluminum alloys of Al-Mg system have a high corrosion resistance, but scientific researches show that they are characterized by pitting corrosion even under atmospheric conditions. Therefore, various coatings for their protection are used, including coatings obtained by chemical oxidation method. In this paper, studies of chromate-free inhibited IFKhANAL-3 conversion coatings were carried out in the G-4 humidity chamber in combination with electrochemical impedance spectroscopy, conductometric analysis and X-ray spectral microanalysis. This made it possible to identify the factors of the beginning of the corrosion process and, in particular, to show the absence of corrosion inhibitor desorption during testing. It was shown that the addition of 1,2,3-benzotriazole into the converting solution contributes to both an increase in the active resistance (Rf) of the oxide film and a later appearance of the first corrosion damage on the coating in comparison with unmodified coatings. According to the conductometric analysis data, it has been shown that a decrease in the porosity of the coatings is observed during the G-4 humidity chamber tests.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>алюминий</kwd><kwd>конверсионные покрытия</kwd><kwd>бесхроматные технологии</kwd><kwd>питтинговая коррозия</kwd><kwd>ингибиторы коррозии</kwd><kwd>камера влажности</kwd></kwd-group><kwd-group xml:lang="en"><kwd>aluminum alloys</kwd><kwd>conversion coatings</kwd><kwd>corrosion inhibitors</kwd><kwd>chromate-free   technologies</kwd><kwd>humidity chamber</kwd><kwd>electrochemical impedance spectroscopy</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Работа выполнена в рамках Госзадания при финансовой поддержке Министерства науки и высшего образования Российской Федерации.</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">А.А.
