“…Low dimensional materials, such as TiO 2 nanowire, TiO 2 , graphene oxide, and Pb nanoparticle have been coating on the surface for creating superhydrophobicity using drop‐coating process, electrospinning, and immersion method . Recently many literatures reported surface treatments for modifying titanium surface to attain water contact angle greater than 160°, as listed in Table . Comparatively, in this study, the hierarchical structure has nanoscale strips with 200 nm wide, which only provides water contact angle slightly above 150°.…”

A superhydrophobic surface of titanium was fabricated by anodization in sodium chloride solution followed by immersion in perfluorodecyltriethoxysilane. The surface characteristics of the anodic film (morphology, composition, microstructure, and adhesion) were investigated by scanning electron microscopy, transmission electron microscopy, X‐ray photoelectron spectroscopy, and scratch testing. The anodic film was comprised of TiO2 and TiCl3 with a thickness of 50 nm. The anodized titanium surface exhibited a hierarchical structure, which consisted of a microscale horn structure with a nanoscale strip‐overlay. This structure provided superhydrophobicity (water contact angle: 151.9° and sliding angle: 3°) following the immersion process. Furthermore, coverage of the hierarchical structure on the anodized titanium surface was improved by performing surface mechanical attrition treatment (SMAT) to grain‐refine titanium surface which was then anodized and it enhanced a slightly increased water contact angle. The thickness (200 nm) of the anodic film on the SMAT‐pretreated titanium surface was much higher than that on the titanium surface (50 nm). This resulted from a large number of grain boundaries on the surface serving as a fast diffusion path during anodization. However, the adhesion of the SMAT‐and‐anodized film was worse than that formed by anodization only. This is due to a large number of pores within the SMAT‐and‐anodized film.

“…Moreover, the as-prepared super-hydrophobic Ti surfaces exhibited outstanding corrosion resistance in acidic, neutral, and alkaline aqueous solutions. The electrochemical reaction mechanism in super-hydrophobic Ti surface fabrication has been reported by Gao et al [12]. They fabricated a super-hydrophobic Ti surface with a WCA of 158.5 • ± 1.9 • using anodization technique and subsequent modification with the fluoroalkylsilane (FAS).…”

“…Among these methods, coating is a simple and effective way for corrosion protection with low cost. In the past several years, various coating techniques have been studied-like chemical vapor deposition (CVD) [4], plasma treatment [5][6][7][8], thermal spray [9], electrochemical methods [10][11][12][13][14][15][16][17][18], sol-gel [19,20], magnetron sputtering [21][22][23], etc. The above-mentioned methods mostly involve post-treatment or high temperatures in the fabrication process, which can damage the coating and/or substrate with relatively low melting points [24].…”

Corrosion—reactions occuring between engineering materials and their environment—can cause material failure and catastrophic accidents, which have a serious impact on economic development and social stability. Recently, super-hydrophobic coatings have received much attention due to their effectiveness in preventing engineering materials from further corrosion. In this paper, basic principles of wetting properties and corrosion protection mechanism of super-hydrophobic coatings are introduced firstly. Secondly, the fabrication methods by electrochemical surface engineering—including electrochemical anodization, micro-arc oxidation, electrochemical etching, and deposition—are presented. Finally, the stabilities and future directions of super-hydrophobic coatings are discussed in order to promote the movement of such coatings into real-world applications. The objective of this review is to bring a brief overview of the recent progress in the fabrication of super-hydrophobic coatings by electrochemical surface methods for corrosion protection of engineering materials.

“…So superamphiphobic surface preparation via electrochemical treatment has attracted considerable scientific attention [21,22]. Nevertheless, there are only a few reports that electrochemical techniques have been employed to prepare superamphiphobic surfaces on titanium and its alloy, despite that titanium alloy has very important applications in aviation, shipbuilding and defense industries for its good heat resistance, corrosion resistance as well as high specific strength [23].…”
