В данной статье представлены результаты исследований коррозионной стойкости сталей марок 65Г и 45, которые были подвергнуты обработке методом электролитно-плазменного упрочнения (ЭПУ). Основной целью исследования было выявление изменений в коррозионных свойствах сталей в зависимости от типа среды: воды, карбамида, суперфосфата и аммиачной селитры. Исследование показало, что после ЭПУ скорость коррозии стали 45 снизилась в 8 раз по сравнению с исходным образцом, достигая значения 2,58×10−4 мм/год. Для стали 65Г также наблюдалось значительное улучшение коррозионной стойкости, особенно в среде карбамида и суперфосфата. Коррозионный потенциал данных сталей сместился в положительную сторону, что указывает на улучшение защитных свойств поверхности. Поляризационные кривые показали уменьшение коррозионного тока для стали 45 до ЭПУ в растворе пищевой соли с 562,34 µА/см² до 111,75 µА/см² в карбамиде, и до 132,67 µА/см² в суперфосфате. Для стали 65Г до ЭПУ ток коррозии в среде пищевой соли составил 67,23 µА/см², уменьшаясь до 57,28 µА/см² в карбамиде и до 60,73 µА/см² в аммиачной селитре после процесса ЭПУ. Результаты подтверждают, что ЭПУ значительно повышает коррозионную стойкость исследуемых сталей, что делает этот метод обработки перспективным для улучшения долговечности металлических изделий, используемых в агрессивных химических условиях.

This article presents the results of studies of the corrosion resistance of steel grades 65G and 45, which were subjected to electrolytic plasma hardening (EPH). The main objective of the study was to identify changes in the corrosion properties of steels depending on the type of environment: water, urea, superphosphate and ammonium nitrate. The study showed that after EPH, the corrosion rate of steel 45 decreased by 8 times compared to the original sample, reaching a value of 2.58×10−4 mm/year. For steel 65G, a significant improvement in corrosion resistance was also observed, especially in the environment of urea and superphosphate. The corrosion potential of these steels shifted to a more positive value, indicating an improvement in the protective properties of the surface. Polarization curves showed a decrease in the corrosion current for steel 45 before EPH in a solution of edible salt from 562.34 µA/cm² to 111.75 µA/cm² in urea, and to 132.67 µA/cm² in superphosphate. For steel 65G before EPH, the corrosion current in a edible salt environment was 67.23 µA/cm², decreasing to 57.28 µA/cm² in urea and to 60.73 µA/cm² in ammonium nitrate after the EPH process.. The results confirm that EPH significantly increases the corrosion resistance of the studied steels, which makes this treatment method promising for improving the durability of metal products used in aggressive chemical conditions.
