Protective coating with microtubular structure was formed by plasma electrolytic oxidation on aluminum alloy AMg3 (Al–Mg system) in tartrate-fluoride electrolyte. This protective layer was additionally modified using azole group corrosion inhibitors (1,2,4-triazole, benzotriazole) and polymer (polyvinylidene fluoride). The morphology, composition, corrosion mechanism and protective properties of the formed coatings were studied.

Защитное покрытие с микротрубчатой структурой было сформировано методом плазменного электролитического оксидирования на алюминиевом сплаве АМг3 (система Al-Mg) в тартратно-фторидном электролите. Данный защитный слой был дополнительно модифицирован с использованием ингибиторов коррозии азольной группы (1,2,4-триазол, бензотриазол) и полимера (поливинилиденфторид). Изучены морфология, состав, механизм коррозии и защитные свойства сформированных покрытий.
