Thanks to its excellent mechanical properties, magnesium alloys have many potential applications in the aerospace and other fields. However, failure to adequately solve corrosion problems of magnesium alloy becomes one of the factors restricting its wide use in many industrial fields. Inspired by nature, researchers designed and fabricated bio-inspired water-repellent (superhydrophobic and slippery liquid-infused porous surface) surfaces with special wetting properties by exploring the surface microstructures of plants and animals such as lotus leaf and nepenthes pitcher, exhibiting excellent corrosion-resistant performance. This article summarizes the research progress on corrosion resistance of magnesium alloys with bio-inspired water-repellent properties in recent years. It mainly introduces the corrosion reasons, types of corrosion of magnesium alloys, and the preparation of magnesium alloys with bio-inspired water-repellent properties to improve corrosion resistance. In particular, it is widely used and effective to construct water-repellent and anti-corrosion coating on the surface of magnesium alloy by surface treatment. It is hoped that the research in this review can broaden the application range of magnesium alloys and provide a powerful reference for the future research on corrosion resistance of magnesium alloys.

“…However, current density does not always relate positively in terms of coating superhydrophobicity and anti-corrosion performances. Liu et al [47] prepared a coated steel where the current density was low. It was found that the deposited crystals were sparse and uneven as the nanostructure could not grow further, but at an increased current density, micro-nano dual-scale structures were formed due to the growth of bud structures and eventually increases the hydrophobicity.…”

“…The water contact angle was 154.21˚ and the sliding angle less than 5˚, respectively. Liu et al [47] prepared a Cu-Ni superhydrophobic coating by immersing 316 l stainless steel in NiCl 2 , H 3 BO 3 , and CuCl 2 electrolytic solution at a current density (8 A/dm 2 for 20 min) and found that dense branch-like structure was deposited on the matrix, shows the surface morphology in (Figure 6(a) and Figure 6(b)). Structure size was about 4 -8 micrometer, and dendrite structure was 300 -600 nm, with water contact angle 161.27˚ and sliding angle 7.8˚.…”

In recent years, superhydrophobic media has attracted tremendous attention due to its industrial applicability value, especially in anti-corrosion performance. The superhydrophobic coating, which has a robust and water-repellent capacity, can catch the air to form several "airbags" on the substrate's surface, isolating the corrosion media. Various superhydrophobic coating preparation technologies have been suggested, but each has its own set of flaws. On the other hand, electrodeposition, as a relatively mature industrial processing application, offers distinct advantages. However, until now, there have been few reviews on the electrodeposition preparation of anticorrosive superhydrophobic coatings. Therefore, the author has described several fabrication techniques based on superhydrophobic coatings in this review, including the advantages and disadvantages. Superhydrophobic coatings conventional concepts and wettability, as well as the model wetting concepts, have been reviewed. The coating processing status and the corrosion-resistant potential through the electrodeposition of metal and comparable composite are detailly encapsulated. Furthermore, electrodeposition parameters, including current density, crystal modifiers, and a deposition time of the coating morphology, are reported, following the ultrasonic-assisted, jet, pulse, and magnetic field-induced electrodeposition, respectively, as the recently developed technologies for preparing a coating. Finally, technology limitation is shown as well as the obstacles and prospects, and the improvement of the superhydrophobic coating's durability as a prospects research focus has been recommended.

“…Self-cleaning is an important and interesting property of superhydrophobic surfaces which contain the rough surfaces, which is crucial for self-cleaning through compositing with photocatalyst and the low surface energy. Recently, a superhydrophobic Cu-Ni coating was produced by Liu et al [32] through the combination of electro-deposition and myristic acid modification. Through the experiment, the combination of hierarchical structure and low surface energy of the treated surface results that the contaminants can be easily removed showing the excellent self-cleaning.…”

As the mimic biology becomes more and more important in the field of technology, superhydrophobic materials in the natural world have also become common. Superhydrophobic surfaces are used to prevent water droplets from wetting themselves which contain the micro-and nano-structures named hierarchical surfaces and exhibit the high water contact angles (WCA) that are greater than 150˚ and perfect application foreground in both our daily lives and industry. In this work, we first discuss several surface properties and their numerical models. And then we list the surface properties of a variety of natural superhydrophobic surfaces and sum up their similarities and differences. The most recent strategies of how to apply natural superhydrophobic surfaces are also introduced within the past several years. In addition, we talk about the limitations of the current generation of superhydrophobic surfaces and prospects which looks for solutions to the problems. This review aims to enable researchers to learn more about the principles and mechanisms of superhydrophobicity and perceive the new methods for creating and modifying it.
