Abstract

Nowadays, magnesium alloys are considered as an alternative to many structural metals such as steel, cast iron, aluminum, and titanium, since they allow decreasing the weight of constructions, giving the strategy for reducing energy consumption. Besides, several thermomechanical parameters for magnesium alloys show to be notably more preferable for technology compared to aluminum alloys and steels. However, the serious problem for the operation of magnesium structures is low corrosion resistance. This review addresses recent research on the corrosion protection efficiency provided by the superhydrophobic coatings fabricated on the surface of Mg-based materials. The colloid-chemical mechanisms of protection by such coatings against both atmospheric and electrolyte corrosion are reviewed in detail jointly with the analysis of the durability of this kind of corrosion protection.
