“…Moreover, an increase in the number of power tubes caused the micro-pits and cracks on the surface of the magnesium alloy to be reduced and resulted in improved corrosion resistance. Qiu et al [191] fabricated a superhydrophobic surface with micro-nano petal-like structure on an AZ31B magnesium alloy by combining WEDM-HS process and surface modification method, with a contact angle and a sliding angle of 151˚ ± 0.5˚ and 4˚ ± 0.5˚, respectively (Fig. 16).…”

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.

“…[23][24][25][26][27] However, because of magnesium's poor corrosion resistance especially in the corrosive medium environment of Cl -, the magnesium alloys' applications are limited. [27][28][29][30][31] Furthermore, containing rare heavy metal elements such as Cu, Ni and Pb, the magnesium alloys are environment friendly and used as the biodegradable metals. [25] As a typical aliphatic polyesters, poly (ε-caprolactone) (PCL) is nontoxic and ecofriendly to living organisms which is widely used in food packaging and pharmaceutical industry.…”

In this study, the degradable superhydrophobic Mg/P/Z/F/H (magnesi-um/poly(-caprolactone)/zinc oxide/1H,1H,2H,2H-perfluorodecyltriethoxysilane (PFDTES)/ heating process) composite materials were prepared through one-step method for enhancing the corrosion resistance of AZ91D magnesium alloys. Electrochemical measurements showed that Mg/P/Z/F/H materials significantly improved the corrosion resistance of magnesium alloys in 3.5 wt.% NaCl. The self-cleaning, adhesion and stability tests suggested that Mg/P/Z/F/H composite materials had well self-cleaning properties, good adhesion strength and stability in wet atmosphere.

“…Magnesium and magnesium alloys, as important engineering materials, are potentially applied in various industrial fields and biomedical applications due to their low density, high strength, and excellent machinability. [1,2] However, they are susceptible to corrosion in seawater or humid atmosphere with organic/inorganic acids, which limits the large-scale application of magnesium and its alloys. [3,4] The application of high-quality surface barrier layers can effectively improve the corrosion resistance of magnesium alloys, such as protective layers obtained by chemical conversion treatment, micro-arc oxidation treatment, electroplating, and electroless plating.…”

A superhydrophobic ceria‐based composite coating is developed to improve anticorrosion properties of AZ61 magnesium alloy, fabricating via chemical conversion method followed by hydrothermal treatment. The cerium conversion coating has a block structure with microcracks. After the hydrothermal treatment, a dense CeO2 layer, porous CeO2 nanorods, and stearic absorbing layers are grown stepwise on the conversion coating. And the composite coating is hydrophobic or even superhydrophobic and has almost no microcracks. As the hydrothermal reaction time increases, the water contact angle of the composite coating first increases and then decreases, and it reaches the maximum value of 152° after hydrothermal treatment for 4 h. Both the dense CeO2 layer and the superhydrophobic stearic absorbing layer can effectively prevent the electrolyte from contacting the substrate; the corrosion current density of the superhydrophobic composite coating is lower than that of the hydrophilic composite coating and the cerium conversion coating, and has the best corrosion resistance.
