Abstract: This review continues the analysis of studies devoted to various methods of obtaining superhydrophobic surfaces on aluminum alloys. A phenomenon known in nature as the “lotus effect” refers to surfaces that are difficult to wet, and the edge angles of wetting with water exceed 150°. Such surfaces are characterized by a binary structure on the micro- and nanometer scales. This structure allows trapping a large amount of air, which significantly reduces the actual contact area between a solid surface and water droplets. Such polymodal roughness is achieved by pre-etching aluminum alloys in solutions of alkalis and acids, surface oxidation, anodizing, or nanosecond laser treatment. Next, the surface is modified in solutions of organosilicon compounds. It is known that studies on organosilanes began back in the 1990s not only to protect aluminum and its alloys from corrosion, but also to impart superhydrophobic properties to their surfaces. The review examines studies on the creation of superhydrophobic surfaces on aluminum alloys, published in the period from 2005 to 2025.
