A novel combined method for fabrication of stable corrosion resistance superhydrophobic surface on Al alloy

A Synergistic Effect between Stearic Acid and (+)-α-Tocopherol as a Green Inhibitor on Ferritic Stainless Steel Corrosion Inhibition in 3.0% NaCl Solution

“…There exists a 'wide palette' of approaches on how to achieve a superhydrophobic surface [20], such as the sol-gel method, electrospinning, electrochemical methods, and layerby-layer method, which can be found in various review articles, like Darband et al [21] and Guo et al [22]. It has been confirmed that surfaces with hydrophobic properties can be an effective corrosion protection for numerous types of metal, such as steel [11,19,[23][24][25][26][27][28][29][30][31], copper [10,[32][33][34][35][36][37], nickel [38], zinc [39,40] Al-alloys [41][42][43][44][45][46] and Mg-alloys [47][48][49][50][51]. Carboxylic acids have been used to create hydrophobic surfaces on many different metal substrates [52][53][54][55].…”

Corrosion Resistance and Formation Mechanism of Anodic Oxidation–Organic Structure Super‐Hydrophobic Self‐Assembled Film

“…Due to the uneven surface and different roughness of the sample, the resulting frequency reduction phenomenon, therefore, the constant phase element (CPE) is used in the equivalent circuit. [12,22] According to the pressure drop of the obtained Nyquist diagram, in order for the constant phase elements to be converted, the coating capacity and the doublelayer capacity are calculated using Equation (8). C represents capacitance; CPE, R, and n represent non-ideal capacitance, resistance, and capacitance coefficient, respectively.…”

“…[9] In recent years, many researchers have conducted more in-depth research on the properties of super-hydrophobic surfaces. [10][11][12][13] Many excellent physical and chemical properties are shown by superhydrophobic surface, such as, anti-icing, heat transfer, and self-cleaning, [14] but few have been used in the field of metal surface corrosion protection. In order to improve the corrosion resistance of Al alloy, the preparation of super-hydrophobic film on Al alloy surface is considered to be the effective protection method.…”

“…In order to improve the corrosion resistance of Al alloy, the preparation of super-hydrophobic film on Al alloy surface is considered to be the effective protection method. [5,12] Generally, the two-step method-based Cassie mode contacts were recognized as a classic super-hydrophobic preparation method; the first step is a rough surface structure prepared, and the second step is surface modification. [15] Therefore, the first step is to build a rough structure through anodizing, which can act as an intermediate layer, improve adhesion, and provide an interface for the organic coating.…”

One‐pot fluorine‐free superhydrophobic surface towards corrosion resistance and water droplet bouncing

“…Figure 7a,b present the Nyquist plots and fitting curves of superhydrophobic 5083 Al alloy and initial 5083 Al alloy, indicating typical semicircles attributed to the charge-transfer control of corrosion reactions. [30] The Nyquist plots of the initial and superhydrophobic 5083 Al alloy features capacitive characteristics. The diameter of the capacitive loop was usually proportional to corrosion rate, that is, the greater the diameter, the lower the corrosion rate.…”
