Recent progress in superhydrophobic and superamphiphobic coatings for magnesium and its alloys
Viswanathan S. Saji
Abstract
Superhydrophobic coatings are projected as a practical approach to tackle the weak aqueous corrosion resistance of Mg/Mg alloys. The present review provides the most recent updates in this area. The various low surface energy treatments reported are presented first, followed by the methods employed for developing hierarchical surface micro/nanostructuring. Reported works in different application areas, including anti-corrosion, biomedical and anti-icing are systematically discussed. Concise descriptions of self-healing characteristics and long-term durability of the superhydrophobic surfaces provided. Reports on superamphiphobic surfaces also deliberated.
