Raziskava je bila usmerjena v razvoj superhidrofobnih aluminijastih površin z uporabo kombinacije laserskega strukturiranja in hidrofobnih premazov (PDMS in HDPA). Pripravljene so bile različne serije vzorcev, ki so se razlikovale po stopnji hrapavosti in vrsti premaza. Njihove lastnosti smo ovrednotili z meritvami kotov omočenja, kotov zdrsa ter z adhezijskimi preizkusi ledu. Rezultati so pokazali, da pri primerljivih kotih omočenja nižja hrapavost pogosto pomeni nižjo adhezijo. Vendar pa to ne velja univerzalno, saj srednje hrapave površine v določenih primerih izkazujejo zelo visoko adhezijo ledu. Naloga tako prispeva k razumevanju razvoja trajnih in učinkovitih površinskih obdelav za zmanjševanje posledic zmrzovanja. This thesis addresses the issue of water freezing and ice adhesion on surfaces, which represents a significant challenge in aviation, energy, and transportation infrastructure. The research focused on the development of superhydrophobic aluminum surfaces using a combination of laser texturing and hydrophobic coatings (PDMS and HDPA). Several series of samples were prepared, differing in surface roughness and coating type. Their properties were evaluated by measuring water contact angles, sliding angles, and ice adhesion strength. The results showed that, at comparable contact angles, lower roughness often corresponds to lower ice adhesion. However, this is not universally true, as moderately rough surfaces in some cases exhibit very high ice adhesion. The thesis thus contributes to a better understanding of the development of durable and effective surface treatments for mitigating the consequences of icing. adhezija ledu hidrofobni premazi lasersko strukturiranje hrapavost površine superhidrofobnost ice adhesion hydrophobic coatings laser texturing surface roughness superhydrophobicity true false false [U.
