The extensive utilization of metals like stainless steel and aluminium in a multitude of industries such as automotive and aeronautics demands functionalized surfaces with superhydrophobic or superhydrophilic characteristics. In general, those wetting properties can be achieved either by modifying the surface chemistry, by controlling the surface topography or by adapting both simultaneously. In this way, the wetting behaviour can be technically adopted for liquid transportation, self-cleaning- or anti-icing applications. Numerous solutions for these particular challenges are observed in nature, manifested in the surface characteristics of plants and animals through periodic microstructures. In this context, Direct Laser Interference Patterning (DLIP) is considered as an innovative solution to fabricate periodic surface structures with resolutions down to the micro- or submicron scale. In DLIP two or more laser beams are overlapped onto the sample surface to generate an interference pattern with a periodic intensity distribution. Additionally, the spatial period Λ can be easily controlled by modifying the overlapping angle Ɵ between the beams or changing the working wavelength. In this work, a fabrication strategy is employed to generate periodic, high aspect ratio line- and pillar-like microstructures on stainless steel (SS1.4301) and aluminium (AW2024) substrates by the means of two-beam DLIP. For the investigations a solid-state picosecond laser operating at 1064 nm is utilized in conjunction with recently developed optical DLIP head (ELIPSYS®, SurFunction GmbH, Germany) to generate surfaces features exhibiting spatial periods Λ of 6, 10, 30 μm. Due to the variation process parameters (laser fluence, pulse-to-pulse overlap, number of scans) aspect ratios (AR) ranging from 0.1 to 2.0 were obtained. Furthermore, the appearance of high and low frequency laser induced periodic surface structures (LIPSS) have been observed, resulting in multi-scaled surface textures. Afterwards, the wettability of the fabricated topographies is evaluated by static water contact angle (WCA) measurements over period of 45 days. The aim of these investigations is to determine how surface morphology, specifically the depth, periodicity and homogeneity of the structures, impacts wetting behaviour.
