“…The water with huge pressure energy is passed through the small hole nozzle (another change energy device), and then converts the pressure energy into kinetic energy to form a high-speed jet [ 72 , 73 , 74 , 75 , 76 ]. Shi et al [ 77 ] studied the superhydrophobic texture of metal surfaces machined by water jet guided laser (WJGL). Figure 13 demonstrates the schematic diagram of the WJGL process and machined results by them.…”

“…For example, the combination of ultrasonic processing and laser processing can improve the micro-scopic morphology of the micro-structure after processing [ 70 ]. Additionally, the combination of water jet processing and laser processing can reduce the size of the heat-affected area of the laser and enhance the processing accuracy [ 77 ]. However, the existing related mechanisms and models for ultrasonic machining of superhydrophobic surfaces are still relatively lacking.…”

When the water droplets are on some superhydrophobic surfaces, the surface only needs to be inclined at a very small angle to make the water droplets roll off. Hence, building a superhydrophobic surface on the material substrate, especially the metal substrate, can effectively alleviate the problems of its inability to resist corrosion and easy icing during use, and it can also give it special functions such as self-cleaning, lubrication, and drag reduction. Therefore, this study reviews and summarizes the development trends in the fabrication of superhydrophobic surface materials by non-traditional processing techniques. First, the principle of the superhydrophobic surfaces fabricated by laser beam machining (LBM) is introduced, and the machining performances of the LBM process, such as femtosecond laser, picosecond laser, and nanosecond laser, for fabricating the surfaces are compared and summarized. Second, the principle and the machining performances of the electrical discharge machining (EDM), for fabricating the superhydrophobic surfaces, are reviewed and compared, respectively. Third, the machining performances to fabricate the superhydrophobic surfaces by the electrochemical machining (ECM), including electrochemical oxidation process and electrochemical reduction process, are reviewed and grouped by materials fabricated. Lastly, other non-traditional machining processes for fabricating superhydrophobic surfaces, such as ultrasonic machining (USM), water jet machining (WJM), and plasma spraying machining (PSM), are compared and summarized. Moreover, the advantage and disadvantage of the above mentioned non-traditional machining processes are discussed. Thereafter, the prospect of non-traditional machining for fabricating the desired superhydrophobic surfaces is proposed.

“…molecular precursors/nanomaterials), including; chemical vapour deposition, electrospinning and more facile techniques (spray coating, dip coating, spin coating, etc.). [14][15][16][17][18][19][20][21][22] Both classes of techniques have found equal success in fabricating synthetic superhydrophobic surfaces. However, limiting factors relating to complexity, equipment costs and compatible precursor materials can determine the suitability of each technique, specific to the coating/surface requirements.…”

“…Most industries are more inclined to use more advanced and fast laser technologies such as picosecond and femtosecond lasers, but they are costly and not very economical. Ta et al suggested using nanosecond lasers as a cheaper alternative to producing hydrophobic surface [4] even the process is slow and involves several runs because of the low removal rate of the material to resolve the issues related to ultrafast laser texturing. As nanosecond laser technology is versatile and simple to shape, many parameters must, of course, need to be optimised to achieve the best machining performance.…”

The use of lasers in surface engineering has recently made significant progress. The hydrophobic surface is commonly studied because of the application in various fields, including vehicles, aerospace, biomedicine, etc. Since these laser methods require many combination parameters, such as laser power (P), frequency (ƒ), scan speed (ʋ) and laser beam diameter (D), the effect of the parameters must therefore be investigated to produce the hydrophobic condition. This research tries to relate the laser power with the morphological properties and contact angle of the SS316L surfaces. Samples are subjected to laser texturing with different laser power settings. The surface is then characterised by surface roughness, and the contact angle is measured according to a specific time interval. The laser power output and energy density function on the surface and contact angle were investigated in these contexts experimentally. Surface roughness was defined and validated to show that the laser parameters' effect is effective and controllable. This study shows that the laser output intensity significantly contributes to regulating surface roughness and the substrate's wetting activity. The 18W and 24W laser outputs produce a spiked surface with various peaks that cause the surface to become hydrophobic over time because of the air-trap that happens in the valley.
