“…Зависимость времени замерзания от теплового сопротивления представлена на рис. 5, b, кривая 3 соответствует расчетной зависимости t fr (R t ) для капель объемом 19.4 µl и среднего перепада температур между каплей и поверхностью материала T d − T s = 16 K. Отмечается корреляция t fr и R t , что позволяет заключить, что в условиях нашего эксперимента время замерзания в существенной степени определялось величиной теплового потока от капли к поверхности материала, что совпадает с мнением авторов работ [22,23].…”

“…Время замерзания статичной капли на поверхности сверхгидрофобных покрытий также оказывается в разы больше чем на контрольных образцах [20][21][22][23]. Ряд исследователей [20,24] считают, что задержка во времени замерзания связана с кинетикой образования зародышей в переохлажденной капле.…”

“…Ряд исследователей [20,24] считают, что задержка во времени замерзания связана с кинетикой образования зародышей в переохлажденной капле. Другое мнение состоит в том, что задержка времени замерзания связана со снижением теплового потока, направленного из объема капли на поверхность покрытия [22,23], который можно охарактеризовать через тепловое сопротивление между двумя теплопередающими телами. Правильный выбор определяющего механизма замерзания позволяет выбрать оптимальную стратегию создания антиобледенительного покрытия [6].…”

“…Hierarchical micro-/nanostructured materials with various shapes and properties are widely used in different applications like as optical materials [1], low adhesive surfaces [2], abrasion-resistant surfaces, anti-icing films [3][4][5][6], anticorrosion coatings [7][8][9], and in the fabrication of superhydrophobic surfaces [10,11]. The superhydrophobicity phenomenon was first observed in lotus leaves in nature [12,13], and it is frequently used to describe surface properties with a water contact angle (CA) larger than 150 • and sliding angle less than 10 • [14,15].…”

In the present study, the impact of copper substrate grain size on the structure of the succeeding electrodeposited nickel film and its consequent corrosion resistance in 3.5% NaCl medium were evaluated before and after functionalization with stearic acid. Nickel layers were electrodeposited on two different copper sheets with average grain size of 12 and 25 µm, followed by deposition of stearic acid film through self-assembly. X-ray diffraction analysis of the electrodeposited nickel films revealed that the deposition of nickel film on the Cu substrate with small (12 µm) and large (25 µm) grains is predominantly governed by growth in the (220) and (111) planes, respectively. Both electrodeposited films initially exhibited a hydrophilic nature, with water-contact angles of 56° and <10°, respectively. After functionalization with stearic acid, superhydrophobic films with contact angles of ~150° were obtained on both samples. In a 3.5% NaCl medium, the corrosion resistance of the nickel layer electrodeposited on the copper substrate with 25 µm grains was three times greater than that deposited on the copper substrate with 12 µm grains. After functionalization, the corrosion resistance of both films was greatly improved in both short and long immersion times in 3.5% NaCl medium.

“…In recent years, superhydrophobic surfaces, which exhibit a water contact angle (CA) above 150 • and a sliding angle (SA) below 10 • , have aroused an enormous amount of interest in both fundamental research and potential applications because of their unique characteristics, such as self-cleaning [7], anti-icing [8,9], oil-water separation [10,11], antifouling property [12] and anticorrosion [13]. Inspired by biological materials in nature, such as lotus leaves [14], a variety of metallic surfaces with super-hydrophobic property have been fabricated through the combination of surface micro/nano structures and low surface energy materials [15,16].…”

The development of a self-cleaning and corrosion resistant superhydrophobic coating for aluminum alloy surfaces that is durable in aggressive conditions has attracted great interest in materials science. In the present study, a superphydrophobic film was fabricated on an AA5052 aluminum alloy surface by the electrodeposition of Ni–Co alloy coating, followed by modification with 6-(N-allyl-1,1,2,2-tetrahydro-perfluorodecyl) amino-1,3,5-triazine-2,4-dithiol monosodium (AF17N). The surface morphology and characteristics of the composite coatings were investigated by means of scanning electron microscopy (SEM), energy dispersive X-ray spectrum (EDS), atomic force microscope (AFM) and contact angle (CA). The corrosion resistance of the coatings was assessed by electrochemical tests. The results showed that the surface exhibited excellent superhydrophobicity and self-cleaning performance with a contact angle maintained at 160° after exposed to the atmosphere for 240 days. Moreover, the superhydrophobic coatings significantly improved the corrosion resistant performance of AA5052 aluminum alloy substrate in 3.5 wt.% NaCl solution.
