20.500.12556/RUL-161194 Primerjava z različnimi metodami določenih mehansko-fizikalnih lastnosti površinskih sistemov Comparison of the mechanical-physical properties of surface systems determined using different methods Za določanje mehansko-fizikalnih lastnosti površinskih sistemov obstaja več metod, ki se med sabo razlikujejo po principu delovanja, dodatno obstaja še razlika na nivoju obravnave materialov. V naši raziskavi smo z uporabo različnih metod želeli preveriti ali obstaja kakšna smiselna povezava med mehansko-fizikalnimi lastnostmi. V ta namen smo pripravili dvanajst površinskih sistemov, ki so se med sabo razlikovali po vrsti podlage, njeni predpripravi in v uporabljenih premaznih sredstvih ter številu posameznih nanosov. Na teh sistemih smo določali debelino suhega filma, trdoto in mikrotrdoto filma ter odpornost proti razenju, mikrorazenju, udarcu in obrabi. Mehansko-fizikalne lastnosti testiranih površinskih sistemov so se zaradi različnih načinov obdelave, uporabljenih premaznih sredstev in podlage močno razlikovale. S pomočjo statistične analize smo tudi dokazali povezavo med mehansko-fizikalnimi lastnostmi. Trdota filma in odpornost sistema proti udarcu sta premo sorazmerni z debelino suhega filma. Odpornost proti razenju in udarcu ter trdota filma so v premem sorazmerju z odpornostjo proti obrabi. Odpornost proti mikrorazenju je v obratnem sorazmerju z debelino suhega filma, trdoto in odpornostjo proti razenju ter udarcu. There are several methods for determining the mechanical-physical properties of surface systems, which differ from each other in terms of the principle of operation, and there is also a difference in the level of material evaluation. In our study, we wanted to use different methods to test whether there is a meaningful correlation between the resulting mechanical-physical properties. To this end, we prepared twelve surface systems that differed in the type of substrate, its pre-preparation, the coatings used and the number of individual applications. We used these systems to determine the thickness of the dry film, the hardness and microhardness of the film as well as the scratch, micro-scratch, impact and wear resistance. The mechanical-physical properties of the analysed surface systems differed greatly due to the different processing methods, the coating agents used and the substrate. With the help of a statistical analysis, we were also able to prove the linear correlation between the mechanical-physical properties. The hardness of the film and the impact resistance of the system are directly proportional to the thickness of the dry film. The scratch and impact resistance as well as the film hardness are directly proportional to the wear resistance. The micro-scratch resistance is inversely proportional to the dry film thickness, the hardness and the scratch and impact resistance. les površinska obdelava premazi mehansko-fizikalne lastnosti wood surface finishing coatings mechanical-physical properties true false false [Ž.
