20.500.12556/RUL-186693 Zasnova sistema za ovrednotenje degradacije površin pri cikličnem sreženju in odtaljevanju Design of a system for evaluation of surface degradation during cyclical frosting and defrosting V delu je predstavljena zasnova sistema za ovrednotenje degradacije površin. Obravnavane so možnosti pasivnega preprečevanja nastanka sreža z uporabo superhidrofobnih površin. Preučeval se je vpliv večkratnih ciklov zamrzovanja in odtaljevanja na mehansko stabilnost ter obstojnost teh površin. V ta namen je bila zasnovana in izdelana testna naprava ter njeno ohišje z nosilci in mizo, katera omogoča avtomatizirano ciklično testiranje vzorcev. Prav tako je bil zasnovan, sestavljen in ovrednoten meglilni sistem, kateri bo skrbel za visok nivo vlažnosti, kar bi omogočalo simulacijo naravnih okoliščin ter pogojev delovanja. Z razvito napravo je mogoče v nekaj dnevih ali tednih uspešno simulirati večletno obremenitev materialov v realnih pogojih delovanja. The thesis presents the design of a system for evaluating surface degradation. Possibilities for the passive prevention of frost formation using superhydrophobic surfaces are examined. The effect of multiple freeze-thaw cycles on the mechanical stability and durability of these surfaces was investigated. For this purpose, a test apparatus along with its housing, support structures, and stage was designed and manufactured to enable automated cyclic testing of samples. Additionally, a misting system was designed, assembled, and evaluated to maintain high humidity levels, allowing for the simulation of natural operating conditions. With the developed apparatus, it is possible to successfully simulate multi-year material exposure under real operating conditions within a matter of days or weeks. degradacija površin sreženje superhidrofobnost kondenzacija desublimacija surface degradation frosting superhydrophobicity condensation desublimation true false false [A.
