Recent progress in superhydrophobic and superamphiphobic coatings for magnesium and its alloys

摘要

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.
