“…Furthermore, it is possible to construct a water-repellent surface from a hydrophilic substrate without chemical modification in laboratory [2,30,31]. In our previous work, the contact angle was increased from 68.5°to 130°on a steel surface by using laser patterning process [1].…”

“…Various surface modifications designed to form hydrophobic surfaces on copper, include the formation of Cu 2 (OH) 3 NO 3 [8], immersion in oxalic acid followed by chemical modification with a siloxane compound [9] and combined chemical etching and polymer plating [10]. The preparation of superhydrophobic metal surfaces can be achieved by surface roughening [11]. Surface modification was also achieved by applying stearic acid to a surface [12].…”

The surface of freshly etched copper and bronze samples was modified by immersion in ethanol solutions of myristic (tetradecanoic) acid. Modification resulted in the formation of hydrophobic layers with contact angles up to 141°. Two kinds of surface structure were observed. The modified surface of copper was covered by a uniform layer containing nano-grains or knitted-like structure, whereas the modified surface of bronze was covered by a layer with lamellate patterns and nano-grains. The corrosion properties of bare and modified copper and bronze surfaces were tested by potentiodynamic polarization experiments in 0.014 M Na 2 SO 4 ? 0.024 M NaHCO 3 solution. The deduced effectiveness of corrosion inhibition by the modified layers on copper and bronze was up to 97 and 68%, respectively. Modification of the surface by immersion in an ethanol solution of myristic acid appears to be a promising treatment for improving the corrosion resistance of copper. The same treatment was not very effective when used on bronze.

“…The surface wettability is determined by its chemical composition and microstructure [10,11]. Major approaches to preparing superhydrophobic surfaces have included hydrothermal synthesis [12], sol-gel method [13], spray-coating [14], electroplating [15], and chemical etching [16], etc.…”

In this paper, hydrophobic modification of magnesium hydroxide film prepared by cathodic deposition on ME20M Mg alloy was achieved with ethanol solution of stearic acid. The effects of solution concentration, temperature and treatment time on the surface wettability were investigated. The corrosion behaviors of typical samples were evaluated by droplet test, total immersion corrosion test as well as PDP (Potentiodynamic Polarization) and EIS (Electrochemical Impedance Spectroscopy) techniques, respectively. Adhesion of coatings to the substrate were examined by tape test. The surface morphology and chemical composition of typical coatings were characterized by SEM, FTIR and XRD respectively. The results indicate that the superhydrophobic surface with 151.5° water static contact angle and 1° sliding angle could be fabricated successfully by simple immersion in a low-concentration stearic acid solution for a short period. Compared with blank sample, the composite surface modification based on cathodic deposition (CD) plus hydrophobic treatment (HT) extended the discoloration time in droplet tests by nearly 25 fold, decreased the icorr (corrosion current density) by three orders of magnitude, and increased the characteristic impedance modulus at 0.1 Hz by nearly four orders of magnitude, indicating that the CD/HT composite surface modification could enhance the corrosion resistance of Mg alloy significantly.
