Due to their superior water-repelling effects, superhydrophobic surfaces have received increasing attention as a promising solution to corrosion of metallic materials. The present article introduces the fundamental theories behind superhydrophobicity followed by a comprehensive review of the recent progresses of this rapidly growing field over the past 5 years. A critical discussion over anticorrosion mechanisms of superhydrophobic surfaces is also provided. For many realistic applications, future efforts are pressingly demanded to prolong the corrosion resistance of these superhydrophobic surfaces. To this end, several important strategies and examples in designing stable, selfhealable, or inhibitor-loaded superhydrophobic surfaces are discussed.

“…In order to achieve super hydrophobic behavior on pure Mg, Wang et al used a two stepped chemical etching treatment. 25 The authors obtained a flowerlike microstructure on the surface, which entrapped air in the surface and became water repellent. On the other hand, Liu et al incorporated laser texturing with chemical etching to generate super hydrophobic surfaces on AZ91 Mg alloy.…”

Laser surface structuring of AZ31 Mg alloy for controlled wettability

Structured surfaces exhibit functional properties that can enhance the performance of a bioimplant in terms of biocompatibility, adhesion, or corrosion behavior. In order to tailor the surface property, chemical and physical methods can be used in a sequence of many steps. On the other hand, laser surface processing can provide a single step solution to achieve the designated surface function with the use of simpler equipment and high repeatability. This work provides the details on the surface structuring of AZ31, a biocompatible and biodegradable Mg alloy, by a single-step laser surface structuring based on remelting. The surfaces are characterized in terms of topography, chemistry, and physical integrity, as well as the effective change in the surface wetting behavior is demonstrated. The results imply a great potential in local or complete surface structuring of medical implants for functionalization by the flexible positioning of the laser beam.

A superhydrophobic surface with chemical and long-time stability was fabricated on AZ31 magnesium alloy in a single-step via hydrothermal synthesis to improve corrosion resistance. The as-prepared surface repelled aqueous solutions with a static water contact angle of 156.7 • , and its superhydrophobicity was maintained for more than one year. The superhydrophobic surface showed anti-icing performance in a cold environment. The electrochemical measurement showed the superhydrophobic coating surface improved corrosion resistance for the Mg alloy substrate in 3.5 wt% NaCl solution. In this study, we sought higher efficiency and environmental friendliness to enhance the prospects for application of magnesium alloys. © The Author(s) 2016. Published by ECS.

Published February 3, 2016 Magnesium alloys are among the lightest and most easily machined metals. Owing to their low density, good electromagnetic screening ability, high strength/weight ratio, low cost, machinability, recyclability and other advantages, Mg alloys are known as the green engineering material of the 21st century.1-3 They are used in many types of applications, such as in the automobile industry, biological materials, aerospace and aircraft fields, and electronic production. [4][5][6] The AZ31 Mg alloy is the most widely used industrial wrought Mg alloy due to its balance of properties and price; it is usually rolled into plate, squeezed into bars or processed by forging.7 However, Mg alloys have shortcomings that limit their application, including low standard potential, high chemical activity, ease of oxidation, low abrasion performance, and susceptibility to corrosion in humid environments. 8 The development of corrosion-resistant Mg alloys will enable a much wider range of applications based on these materials. So far, many approaches have been used for conferring corrosion resistance on magnesium alloy; for example, the control of metallurgical factors by increasing the purity of the alloy, 9 mixing with rare earth elements, 10 or the use of a rapid solidification processing have been investigated.11 Alternative approaches for facilitating corrosion-resistance performance include surface modification by laser processing, the deposition of a protective coating layer by a sol-gel route, anodic oxidation, electroplating and spraying oil paint.12-14 Recently, many studies have shown that superhydrophobic surfaces are effective for conferring corrosion resistance.
