Защита металлов тонкими гидрофобными покрытиями
https://doi.org/10.61852/2949-3412-2025-3-2-148-168
Аннотация
В статье рассматривается возможность гидрофобизации поверхности металлов и сплавов, как способ замедления их коррозии в агрессивной среде. Эффективность гидрофобной обработки во многом зависит от природы металла, гидрофобного реагента и растворителя. В некоторых случаях возможна пассивация металлов. Формирование тонкого гидрофобного защитного покрытия на металлах осуществляется не только из органических, но и водных растворов, в которых важную роль играет хемосорбция гидрофобного агента. Показана возможность повышения устойчивости гидрофобной поверхности алюминиевого сплава АМг6 и его пассивного состояния при обработке водным раствором олеилсаркозината натрия с добавлением в него аминоэтиламинопропилтриметоксисилана. Рассмотрены способы гидрофобизации меди и ее зашита триазолами, тиазолами и смесевыми ингибиторами коррозии на их основе, а также алкантиолами.
