Ингибиторы коррозии используются не только как самостоятельные средства защиты, но и для повышения антикоррозионных свойств лакокрасочных и конверсионных покрытий на алюминиевых сплавах. Использование супергидрофобных (СГФ) покрытий является достаточно перспективным и эффективным методом защиты металлов и сплавов, тем не менее, невысокая устойчивость СГФ слоев в водных средах значительно ограничивает их практическое применение. В настоящей статье рассматривается комбинированный способ защиты от коррозии алюминиевого сплава Д16 в хлоридных растворах. Метод основан на повышении устойчивости и сохранении СГФ свойств покрытий стеариновой и октадецилфосфоновой кислот путем внесения небольших добавок ингибиторов (солей редкоземельных металлов церия и иттрия).

Corrosion inhibitors are used not only as separate protective agents, but also to enhance the anticorrosive properties of paint and conversion coatings on aluminum alloys. The use of superhydrophobic (SHP) coatings is a fairly promising and effective method of protecting metals and alloys, however, the low stability of SHP layers in aqueous media significantly limits their practical application. This article discusses a combined corrosion protection method for aluminum alloy D16 in chloride solutions. The method is based on increasing the stability and preserving the SHP properties of coatings made from stearic and octadecylphosphonic acids by adding small additives of inhibitors (salts of rare-earth metals cerium and yttrium).
