Abstract:With the development of technology, magnesium alloys have been concerned increasingly as the engineering material. Owing to its special functional properties, superhydrophobic magnesium alloys have a wide application prospect in the field of microfluidic transport, self-cleaning and anti-icing. The wettability mechanism of superhydrophobic surfaces was explained in detail. The preparation processes of the bio-inspired superhydrophobic magnesium alloys were also summarized while the possibility of its industrialization was evaluated. The research and the mechanism of corrosion property of the superhydrophobic magnesium alloys were sum up. Meanwhile, in consideration of the combination of anti-corrosion property and anti-adhesion property of the superhydrophobicity and the magnesium alloys with great biocompatibility, the research interests of the superhydrophobic magnesium alloys were discovered.
