В последнее время показано, что перспективным и весьма эффективным способом защиты металлов и сплавов от коррозии являются супергидрофобные покрытия. Несмотря на то, что их практическое применение в настоящее время весьма ограничено, в виду сложности их получения и высокой стоимости реагентов – поиск доступных и экологически безопасных способов гидрофобизирующей обработки поверхности имеет большое значение. Широко известно, что алкилкарбоксилаты, особенно их высшие гомологи являются эффективными пассиваторами и ингибиторами коррозии различных металлов, в том числе и алюминиевых сплавов. В обзоре обсуждается возможность получения супергидрофобных покрытий на алюминиевых сплавах после получения на их поверхности шероховатой структуры (в результате химического травления, анодирования, лазерного текстурирования, механической обработки), а затем ее модификации в этанольных и водно-этанольных растворах нетоксичной стеариновой кислоты.

Recently, it has been shown that superhydrophobic coatings represent a promising and highly effective approach for protecting metals and alloys from corrosion. Although their practical application is currently rather limited due to the complexity of their production and the high cost of reagents, the search for affordable and environmentally friendly methods of surface hydrophobization is of great importance. It is widely known that alkyl carboxylates, especially their higher homologs, are effective passivating agents and corrosion inhibitors for various metals, including aluminum alloys. This review discusses methods for obtaining superhydrophobic coatings on aluminum alloy surfaces by first creating a rough surface texture (via chemical etching, anodizing, laser texturing, or mechanical treatment), followed by modification using non-toxic stearic acid in ethanol and aqueous-ethanol solutions.
