“…This method is capable of providing information about corrosion rate, corrosion mechanisms, and even the susceptibility of materials to corrosion under stimulated environments [19,92]. The working mechanism of polarization method involves varying the potential of the test sample, which acts as the working electrode, and plotting the current produced as a function of either potential or time [93][94][95].…”

Engineered superhydrophobic coating for anti-corrosion applications is a subject of great significance at present. However, the use of superhydrophobic coatings for anti-corrosion applications is hindered by the mechanical durability in many cases. There is a need for an understanding not only of how to fabricate such surfaces, but also of the corrosion resistance and mechanical durability of those coatings. This review discusses recent developments in the mechanical durability of superhydrophobic coatings primarily used for anti-corrosion. First, superhydrophobicity is introduced with an emphasis on different wetting models. After that, this review classifies the nanofabrication methods based on the material and methods of surface functionalization. Furthermore, the testing procedures used for the measurement of corrosion and mechanical durability are presented. Finally, the mechanical durability and anti-corrosion performance of the developed superhydrophobic coatings are discussed.

A superhydrophobic surface featuring high roughness and low surface energy is designed for effective corrosion protection on aluminum via a facile and cost-effective electrochemical route. The effects of the electrolyte composition and electrodeposition time on the surface wettability were investigated. Moreover, the corrosion resistance performance of the as-prepared superhydrophobic aluminum surface was studied using electrochemical impedance spectroscopy and electrochemical noise techniques. The results show that the superhydrophobic aluminum surface obtained at 2 V for 20 min has a high static water contact angle of 155.8°. Both the average corrosion rate and pitting intensity are remarkably inhibited by the as-prepared superhydrophobic surface on aluminum. Moreover, the static water contact angle for the obtained superhydrophobic surface remains above 150°after exposure to 3.5 wt% NaCl solution for 30 days. This facile and economical superhydrophobic surface, with its excellent anti-corrosion property and stability, shows significant potential for use in industrial applications.

“…Several ways for enhancing the corrosion protection were discussed in the literature, including the formation of thick oxide films and the formation of a superhydrophobic layer atop of bulk copper . As for oxide films on copper and copper alloys, typically the ionic state of copper can be either monovalent or divalent, associated with the formation of cuprous oxide Cu 2 O or cupric oxide CuO, respectively.…”

anions such as chloride ions. [1,2,[4][5][6][7] This can compromise using bare copper and its alloys in technology because corrosion of copper impacts its performance in industrial and technological applications.Several ways for enhancing the corrosion protection were discussed in the literature, including the formation of thick oxide films [3,8,9] and the formation of a superhydrophobic layer atop of bulk copper. [10][11][12][13][14][15][16][17][18][19] As for oxide films on copper and copper alloys, typically the ionic state of copper can be either monovalent or divalent, associated with the formation of cuprous oxide Cu 2 O or cupric oxide CuO, respectively. In many cases, such as high temperature or anodic oxidation, the dual oxide phase formation takes place, with CuO occupying the outer and Cu 2 O the inner layers. [8,9,20,21] Such complex oxide layer has been found to be useful in improving the corrosion resistance of copper in NaCl solutions, [1,2,8,22] while the formation of a compact thick film of CuO on Cu surface prevents anodic corrosion. [23] The superhydrophobic films on metal surfaces essentially inhibit the electrochemical corrosion processes due to several protection mechanisms, such as electrolyte repellency, suppression of adsorption of aggressive ions onto the surface, barrier effect of the modified textured surface layer, and specific charging of a hydrophobic surface in electrolytes. [24,25] At the same time, for the majority of designed superhydrophobic coatings, a poor abrasive resistance restricts the practical application of these coatings. However, it was shown recently [26] that a strategy, combining the laser chemical modification of metal's surface layer and laser texturing, followed by chemisorption of low energy compounds, can be effectively used to control the mechanical and chemical properties of a superhydrophobic layer on aluminum substrate.In this study, we will demonstrate that the coatings with enhanced protective properties based on multibarrier principle can be designed on copper using the above strategy. We will show that nanosecond laser treatment in an oxygen atmosphere under appropriate laser texturing regimes followed by chemisorption of fluorooxysilane allows obtaining a thick layer of cupric oxide CuO with crystalline micro-and nanotexture and superhydrophobic properties. Triple layer copper oxide structure designed in that way allows solving the problem of durable polyfunctionality of superhydrophobic coatings. We will present Copper and its alloys are among the most used metals for the industry. However, using bare copper and its alloys in technology is compromised because corrosion and poor abrasion resistance of copper impacts its performance in industrial and technological applications. In this paper, a strategy based on combining the laser chemical modification of metal's surface in a controlled atmosphere and laser texturing, followed by chemisorption of low energy compounds is effectively used for fabrication of a superhydrophobic coating with enhanced prot...
