The study on corrosion resistance of superhydrophobic coatings on magnesium

A Review on Applications of Superhydrophobic Coatings

“…They prepared biocompatible Mg-Mn layer doubled hydroxide (LDH) film first on the pure magnesium through electric field-assisted immersion method, then this myristic acid and calcium chloride was electrodeposited on the prepared sample superhydrophobic layer get prepared. They got a 154.3-degree water contact angle and found that due to superhydrophobic coating there was a significant enhancement in corrosion resistance property [48]. In another experiment, Alghanab et al used electroless Nickel-Phosphorus coating on AM60B magnesium alloy using layer double hydroxide (LDH) as under layer to enhance its corrosion resistance property.…”

Superhydrophobic Silane/Fluorinated Attapulgite@SiO2 Composite Coatings on Magnesium Alloy for Corrosion Protection

“…[5,48] In addition, the corrosion resistance of the superhydrophobic coating is related not only to the air cushion, but also to the physical and chemical properties of the interface between the coating and the corrosive medium. [12] The coating contains a large number of hydrophobic fluorinated groups and they have two main functions at the interface with corrosive media. It contains mounts of Cl À , H 2 O and dissolved O 2 in the corrosive media as shown in Figure 14.…”

“…[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.…”

One-step fabrication of soft calcium superhydrophobic surfaces by a simple electrodeposition process

“…23 Meantime, calcium, the third most abundant metal in nature, had a decisive advantage over the other metals due to its peculiar coordination chemistry. Although certain research about superhydrophobic surfaces, including calcium elements, has been reported in the literature, [24][25][26] to our knowledge, few studies have systemically reported about calcium superhydrophobic surfaces including preparation and certain impacting dynamic behaviors of water droplets, and their underlying mechanism is still not entirely clear.…”
