Superhydrophobic surface of Mg alloys: A review

In the present review, the formation of superhydrophobic (SHP) structures on the surface of Mg alloys was investigated. Different methods including hydrothermal technique, chemical and electrochemical deposition, conversion and polymer coating, and etching routes were discussed. The superhydrophobicity could form on the surface of Mg alloys by the application of different chemical, electrochemical, and physical methods followed by the immersion of these alloys in the solution containing modifying agents including fatty acids or long-chain molecules. The formed morphology, composition, and contact angle were reported and the effect of synthesis route on these characteristics was reviewed.
