“…This manifests that the chemical reaction between –COOH groups in STA and Al–OH at the aluminum alloy surface has taken place successfully. [ 23,24 ] Consequently, CH 3 (CH 2 ) 16 COO–Al generates at the aluminum alloy surface. Therefore, the long alkyl chains have been grafted onto the aluminum alloy surface via chemical bonds.…”

It is urgently necessary to seek more simple and effective methods to construct superhydrophobic metal surfaces to improve the corrosion resistance and antifouling performance. Herein, a facile method for fabricating superhydrophobic aluminum alloy surface is developed via boiling water treatment and stearic acid modification. It is noteworthy that no prepolishing on aluminum alloy is required and no caustic reagents and typical equipments are used during the preparation procedure. Therefore, the fabrication method is quite a simple and environment‐friendly technique. Both micro‐ and nano‐scaled binary structure forms at the resultant aluminum alloy surface while long alkyl chains are grafted onto the rough aluminum alloy surface chemically. Consequently, the resultant aluminum alloy exhibits outstanding superhydrophobicity. More importantly, the superhydrophobicity has excellent universality, diversity, stability, excellent corrosion resistance, and antifouling performance. The facile preparation, excellent superhydrophobic durability, and outstanding performance are quite in favor of the practical application.

“…In previous literatures, the superhydrophobic light alloy materials with micro-structured oxide or hydroxide layers was obtained by using hydrothermally treated and selfassembly of 1H,1H,2H,2H-perfluorooctyltriethoxysilane (PFOTES) [40] . As such, Feng et al fabricated the superhydrophobic Mg alloy surface using an environmentfriendly, facile, and cost-effective one-step hydrothermal process [41] . The as-prepared superhydrophobic Mg alloy surface with rough and hierarchical micro-/nanostructure exhibits excellent corrosion resistance and self-cleaning performance (figure 4).…”

Metals and their alloys are irreplaceable engineered materials showing great importance in our society. Light alloy materials (i.e., Mg, Al, Ti, and their alloys) have tremendous application potential in the aerospace, automotive industries, and biomedical fields for they are lighter and have excellent mechanical properties. The corrosion of light alloys is ubiquitous and greatly restricts their utilization. Inspired by the natural anti-water systems, many new designs and conceptions have recently emerged to create artificial superhydrophobic surfaces with great potential for corrosion resistant of light alloy. This review firstly introduces the concept of superhydrophobicity and strategies of producing superhydrophobic surfaces to inhibit the corrosion of light alloys. In addition, we elaborate the durability of superhydrophobic light alloy materials for commercial and industrial applications, and present their anticorrosion mechanism in the corrosive media.

“…[4][5] A rough surface and low surface energy are the two key elements for designing superhydrophobic surface. Up to now, numerous methods of constructing superhydrophobic surface on magnesium alloys have been proposed, such as electrodeposition, [6][7][8][9][10][11][12] micro-arc oxidation, [13][14][15] chemical conversion treatment, [2,16] hydrothermal method, [17][18][19][20][21][22] immersion method, [23,24] laser ablation, [25] electroless plating, [26] dip coating, [27] spray coating, [28,29] et al Among these various methods, spray-coating technique is a fast, facile method to fabricate coatings on a large-scale, which has been widely used in industry for coating complex shapes on different substrates. [28,29] Organosiloxane is a promising candidate for the preparation of wear-resistant superhydrophobic materials due to its polymerization to enhance the mechanical durability and strong adhesion to the substrate.…”

To improve the corrosion resistance of magnesium alloys, superhydrophobic coatings were prepared by employing fluorinated attapulgite@SiO2 (F‐ATP@SiO2) particles and silanes via a facile one‐step spraying technique in this study. Surface morphology, chemical compositions, roughness and wettability of the coatings were comprehensively investigated by Field emission scanning electron microscopy (FESEM), Fourier transform infrared spectra (FTIR), 3D optical microscope and contact angle techniques, respectively. Corrosion resistance of the coatings was evaluated by potentiodynamic polarization test and electrochemical impedance spectroscopy (EIS). Results indicated that the coatings exhibited superhydrophobicity due to its micron scale mastoid structure and low surface energy of F‐ATP@SiO2 particles. The superhydrophobicity and anticorrosion performance of the coatings increased with the dosage increase of F‐ATP@SiO2 particles. The water contact angle of the prepared surface can reach as high as 161° with sliding angle of 4°. Icorr of the coatings can reach 5.519×10−8 A cm−2, decreased by 3 orders of magnitude compared to bare AZ31, which showed excellent anticorrosion performance. With the prolongation of immersion time, the EIS analysis indicated that the anticorrosion property of the coating degraded gradually. Based on the electrochemical analysis, the corrosion protection mechanism of the superhydrophobic coating was proposed.
