Superhydrophobic Coatings on Metallic Substrates I: Magnesium Based

Abstract

Superhydrophobic coatings can not only improve the corrosion resistance of Mg and Mg alloys, but also endow them with many surface functions. However, the vulnerability of the delicate surface textures significantly impedes the practical application of superhydrophobic surfaces. This chapter first introduces robust superhydrophobicity design strategies, including passive resistance and active regeneration strategies, then various approaches for developing superhydrophobic coatings on Mg and Mg alloys and durability issues are highlighted. Finally, the challenges to improving the durability of superhydrophobic coatings on Mg and Mg alloys and future development prospects are summarized.
