“…Recently, more and more attention has been paid to the development of mechanical methods for modifying metal surfaces in order to change wettability properties, in particular to achieve a hydrophobic state. An analysis of research conducted in this area has shown that the use of hydrophobic surfaces created on the basis of mechanical modification of the surface with a subsequent reduction in surface energy helps to reduce hydraulic resistance during the transportation of liquid media [10][11], reduce the rate of ice formation [12], and intensify heat exchange processes [13] and other positive effects.…”

The paper is devoted to the study of the effect of laser processing on the wettability and corrosion resistance of the surface of experimental samples made of AISI 316L sheet steel and samples made by printing from AISI 316L steel powder using selective laser melting technology. As a result of the studies, it was established that laser texturing of the relief with the subsequent formation of molecular layers of surfactants on a steel surface helps to achieve higher contact angle values, however, such treatment leads to a decrease in corrosion resistance.

“…Although their decisive surface topography parameters were different, both works showed that increasing hydrophobicity caused decreasing IAS. In addition, much effort has been devoted to pursue the low-IAS surfaces by altering topography and material simultaneously [ 16 , 44 , 45 ], where the relationship between surface topography and IAS could not be straightforwardly established. Therefore, more study is needed to reveal the role of surface topography in de-icing and the underlying mechanism.…”

It is of great significance to grasp the role of surface topography in de-icing, which however remains unclear yet. Herein, four textured surfaces are developed by regulating surface topography while keeping surface chemistry and material constituents same. Specifically, nano-textures are maintained and micro-textures are gradually enlarged. The resultant ice adhesion strength is proportional to a topography parameter, i.e. areal fraction of the micro-textures, owing to the localized bonding strengthening, which is verified by ice detachment simulation using finite element method. Moreover, the decisive topography parameter is demonstrated to be determined by the interfacial strength distribution between ice and test surface. Such parameters vary from paper to paper due to different interfacial strength distributions corresponding to respective situations. Furthermore, since hydrophobic and de-icing performance may rely on different topography parameters, there is no certain relationship between hydrophobicity and de-icing.

“…Superhydrophobic surfaces have properties such as anti-frost [ 10 ], anti-corrosion [ 11 ], self-cleaning [ 12 ], anti-icing [ 13 ], fluid drag reduction [ 14 ], and enhanced condensation heat transfer [ 15 ]. Due to their extremely low surface energy [ 16 ], superhydrophobic surfaces have great potential for mitigating dust deposition [ 17 ].…”

The self-cleaning ability of superhydrophobic metal surfaces has attracted extensive attention. The preparation of superhydrophobic material using the coating method is a common processing method. In this experiment, aluminum fins were processed by laser etching and perfluorinated two-step coating. The aluminum surface was modified using a femtosecond laser and 1H,1H,2H,2H- perfluorooctane triethoxysilane (PFOTES). A superhydrophobic aluminum surface with excellent mechanical stability and self-cleaning properties was obtained with the superhydrophobic contact angle (WCA) of 152.8° and the rolling angle (SA) of 0.6°. The results show that the superhydrophobic surface has an excellent cleaning effect compared with an ordinary surface in unit time. Then, a wear resistance test of the superhydrophobic surface was carried out by using the physical wear method. The results show that physical wear had a low influence on the hydrophobic property of the specimen surface. Finally, the Vickers hardness analysis found that the superhydrophobic surface hardness was significantly better than the ordinary surface hardness compared with the superhydrophobic surface hardness. Based on the excellent self-cleaning properties, wear resistance, and robustness of superhydrophobic materials, the laser-etched and perfluorinated superhydrophobic aluminum fins designed and manufactured in this study have broad application prospects in improving the heat transfer efficiency of finned heat exchangers.
