To prepare surfaces with stable anti-icing properties, square-column micro/nanocomposite structures were fabricated using wire-cut electrical discharge machining. Smooth and hydrophobic/superhydrophobic surfaces were tested for wettability and were subjected to mechanistic analysis. Droplets were found to produce an `air cushion effect' upon contact with the microstructure, which reduced the contact area between the droplets and the aluminium substrate and increased the contact angle of the drop...

Abstract Collecting water from dew, foggy wind or moisture present in the air recently has been recognized as a method to solve water shortage. In this paper, the directional fog harvesting ability of the pine needles is investigated. Results show that water droplets deposited on the surface of the pine needles can spontaneously move toward the root along the microchannel formed by the groove structure under the Laplace pressure generated by the shape gradient. This process is underpinned by the...

The aluminum alloy 6061 was used as the substrate, and the hydrophobic surface was prepared by wire cut electrical discharge machining (WEDM), and the superhydrophobic surface was obtained by optimizing the processing size. The condensation performance of the three different wettability surfaces under condensing conditions was observed and the mechanism analysis was carried out. The results show: The condensation performance and wettability of the aluminum alloy surface are directly related. Und...

The superhydrophobicity of solid surfaces is primarily dependent on low surface energy and surface microstructure. In order to prepare a low-wetting surface, a micro-column array was constructed on the surface of aluminum by micro-milling and grinding, and the influence of the square-column structure on the surface wettability of the material was analyzed. Milling will cause burrs on the surface of the square column. Under the joint action of the square columns and the burrs on the surface, the ...

In this study, a more conveniently method was tried to prepare T-shaped groove structure surface with HS-WEDM method on the surface of an aluminum alloy, and the results shown that processed surface has super-hydrophobic and high- adhesion properties. The fabricated surface morphology was observed by scanning electron microscopy and laser confocal and it was found that there are some micrometers or submicron-scale pits and mastoids distributed on the surface of the sample with sub-millimeter T-s...

Microstructures of stainless steel surfaces were textured by nanosecond laser. The surface morphology and hydrophobic properties of the stainless steel surfaces were measured by scanning electron microscope (SEM), OCA20 contact angle measuring instrument testing, respectively. It was found that the surfaces of the modified stainless steel achieved superhydrophobicity heated by a drying oven, the static contact angle reached 152 ± 1.3°. Microstructure and chemical elements of superhydrophobic sur...

Using nanosecond laser the bionic groove structures were fabricated on the surface of aluminum alloy. The microstructure of the sample surface and surface wettability were observed by scanning electron microscope (SEM) and OCA20 video optical contact angle measuring instrument, respectively. It was found that the change of groove structure and size on the surface of aluminum alloy material was the main reason for the changes of hydrophobic properties. In addition, the increase of oxygen on the s...

The superhydrophobic surface of aluminium alloy was fabricated by nanosecond laser facility. The surface structures of the specimen were observed by scanning electron microscope and confocal laser scanning microscope. Surface hydrophobicity was evaluated by contact angle of deionised water. The phases present in the aluminium alloy surface were identified by X-ray energy spectrum analysis module of scanning electron microscope. The study showed that, a simple method of the fabrication of superhy...

In order to achieve superamphiphobic surface of aluminium alloy, a method based on laser-EDM (electrical discharge machining) was proposed. By means of laser etching, the size of the controllable micrometre square column structure could be prepared on the surface of aluminium alloy. Then combined with the electric processing method, the binary micro-nano rough structure was constructed and modified with fluorosilane methanol solution, and the superamphiphobic surface was achieved successfully. T...
