“…electrodeposition step was used, which led to the deposition of spherical nickel droplets on the tips of the micro-textures as shown in Figure 4 [46]. Finally, an innovative method to create multi-scale surface textures is to combine two different laser processes, namely DLW and DLIP [76,77]. Thereby, the bigger surface textures are created by DLW and the smaller textures by DLIP.…”

“…Subsequently, the smaller textures were fabricated with a DLIP system on top of the bigger DLW textures using an Nd:YVO4 laser with a pulse duration of 10 ps. The smaller textures showed a periodicity of 2.6 µm and a depth of roughly 1 µm [76]. Another laser process, which has been proposed to create multi-scale textures is the combination of DLW with the controlled generation of laser induced periodic surface structures (LIPSSs) [78].…”

Multi-Scale Surface Texturing in Tribology—Current Knowledge and Future Perspectives

Surface texturing has been frequently used for tribological purposes in the last three decades due to its great potential to reduce friction and wear. Although biological systems advocate the use of hierarchical, multi-scale surface textures, most of the published experimental and numerical works have mainly addressed effects induced by single-scale surface textures. Therefore, it can be assumed that the potential of multi-scale surface texturing to further optimize friction and wear is underexplored. The aim of this review article is to shed some light on the current knowledge in the field of multi-scale surface textures applied to tribological systems from an experimental and numerical point of view. Initially, fabrication techniques with their respective advantages and disadvantages regarding the ability to create multi-scale surface textures are summarized. Afterwards, the existing state-of-the-art regarding experimental work performed to explore the potential, as well as the underlying effects of multi-scale textures under dry and lubricated conditions, is presented. Subsequently, numerical approaches to predict the behavior of multi-scale surface texturing under lubricated conditions are elucidated. Finally, the existing knowledge and hypotheses about the underlying driven mechanisms responsible for the improved tribological performance of multi-scale textures are summarized, and future trends in this research direction are emphasized.

“…in optoelectronics where microstructured surfaces could increase efficiency of solar cells or organic light emitting diodes OLED [Lang 2016]. In addition, surfaces covered with periodic micropattern can exhibit new physical properties, such as hydrophobicity [Cardoso 2018] up to superhydrophobicity [Berger 2016] or hydrophilicity [Zhao 2015]. Microstructures can also enhance biocompatibility of body implants [Kurella 2005] reduce friction of components in automotive industry or generate antiadhesive properties of tools [Rosenkranz 2015].…”

Nanostructuring and microstructuring approaches frequently used in microelectronics manufacturing, such as electron beam lithography or nanoimprint lithography, are considerably slow. In order to reduce processing time, laser patterning methods based on interference of multiple beams have been developed. Within one laser pulse, a significant part of an irradiated area on a sample surface is patterned with desired micro-or submicrostructures. Nowadays, interference patterning goes beyond periodic lines and dots. Controlling the number of interfering beams, orientation of polarization vectors, relative phase shift, and the beam angle of incidence allows to customize the intensity distribution on the sample surface. Simulations of various interference patterns were calculated and verified on CMOS camera using 1030 nm laser diode. Based on these results, dot and line-like interference patterns were directly imprinted on the surface of carbon fiber reinforced polyether ether ketone plate by 1.8 ps, 11 mJ laser pulses at 1030 nm.

Over the years, researchers have been working to mimic the nature by inducing superhydrophobic properties into a variety of material surfaces so that they exhibit non-wetting properties. Many diverse applications have been found in the fields, such as space and aerospace, defence, automotive, biomedical applications and engineering, sensors, apparels, and so on. Superhydrophobic surfaces repel water generally due to their surface texture or chemical properties. In this article, we focus on the functional applications of the superhydrophobic surfaces, and state-of-the-art fabrication technologies and processes, and the limitations of these processes to generate the superhydrophobic surfaces have been developed over the years.
