Within the framework of the diploma thesis, we focused on the development of laser-textured superhydrophobic surfaces with anti-icing properties. The development in the field of icing delay and prevention is currently focused on using passive methods based on surface modification. By reviewing the available literature, we provided the framework for the empiric part of the research, where we developed laser-textured surfaces with favorable anti-icing properties on samples from 1050A aluminium alloy. We evaluated their surface wettability, nucleation temperature, and icing onset delay whilst also tracking the icing process and evaluating the corrosion resistance before comparing them with a reference untreated surface and a solely hydrophobized surface. Laser-textured surfaces that showed the most favorable superhydrophobic properties were surfaces with both deep and shallow channels, with the spacing between consecutive laser passes of 25 µm and 50 µm. We achieved the lowest nucleation temperature of -23,2 °C on a surface with shallow channels with 25µm line spacing. We measured the icing delay at surface temperatures between -20°C and -12,5 °C and confirmed our hypothesis that the icing delay becomes shorter with decreasing surface temperature. On the developed surfaces, we conducted electrochemical tests to evaluate the corrosion resistance of the surfaces. The surface with shallow channels and a 25µm line spacing showed the best corrosion resistance. Compared to the reference surface, we notably improved the anti-icing properties with the hydrophobized laser-textured surfaces.
