Corrosion resistance of composite coatings on low-carbon steel containing hydrophobic and superhydrophobic layers in combination with oxide sublayers

Nanosecond laser micro- and nanotexturing for the design of a superhydrophobic coating robust against long-term contact with water, cavitation, and abrasion

“…Superhydrophobic coatings are designed for use as a passive method of protecting materials and are expected to become a significant alternative to more complex and energy consuming techniques. As shown by experimental, numerical and analytical studies, superhydrophobic surfaces typically have reduced drag in both laminar and turbulent flows [6,7], high corrosion resistance [8][9][10] and stability against certain kinds of mechanical loads [11][12][13][14]. This reinforces the optimistic view that these surfaces could be used in a hazardous medium or conditions of underwater operation, especially in marine environments.…”

Stability and corrosion resistance of superhydrophobic surface on oxidized aluminum in NaCl aqueous solution

“…Compared with the researches on corrosion of SHS [7][8][9][10][11][12] , the methods to investigate the stability of SHS were much fewer. For example, Ou et al [16,17] and Xiong et al [18] proposed a humidity test and a solution immersion test to evaluate the stability and corrosion of SHS, respectively.…”

“…In recent years, superhydrophobic surfaces (SHS) [3][4][5][6] with static contact angle larger than 150° and sliding angle smaller than 10°have attracted considerable interest in alleviating corrosion for engineering materials, such as Ni, Al, Mg, and so on [7][8][9][10][11][12] . The corrosion resistance of SHS is due to the fact that the permeation of corrosive species, such as Cl -dissolved in water, to the metallic matrix can be suppressed greatly by the air pockets on the solid-liquid interface [13,14] .…”

Superhydrophobic surfaces on diverse metals based on ultrafast sequential deposition of silver and stearic acid

“…Typically, surface morphology was firstly tailored by different techniques of anodization [2,3], electrodeposition [4], laser treating [5], electrospinning [6,7], chemical vapor deposition [8], sol-gel processing [9], etc. Then, surface was passivated by low-surface-energy molecules of fluoroalkyl-silane [2,3,[10][11][12], fluoroalkyl mercaptan [4,13], poly(alkyl siloxane) [14], etc.…”
