Magnesium (Mg) alloys show great potential to be extensively applied in practice owing to their superior properties,while the poor corrosion resistance does undoubtedly restrict their applications.Superhy-drophobic coatings with good repellency to corrosive solutions can significantly decrease the interaction between the corrosive species and the substrate,so that they are receiving a lot of attention to improve the corrosion resistance of Mg alloys.Various strategies have been introduced to develop a superhydropho-bic coating on Mg alloys,which were reviewed to elucidate the current research status to provide a clue or thinking for beginning researchers.Further,the existing issues of superhydrophobic coating were dis-cussed,especially for their real applications in practice,mainly owing to their poor mechanical stability.Based on the existing issues,the future study was discussed to improve the stability of hierarchical struc-tures and entrapped air pockets,impart the superhydrophobic coating self-healing property to repair the damaged area during service,provide double protection by incorporation of corrosion inhibitors,or even introduce slippery liquid-infused porous surfaces with lubricant layer to provide better corrosion protection for Mg alloys.
