Annotation: Problematika korózie (napr. v umývačkách riadu vo veľkej gastronómii) a zvetrávania (napr. pri dlhodobom skladovaní a zaoceánskom transporte) úžitkového skla sa v poslednom období stala jedným z kľúčových faktorov konkurencieschopnosti podnikov sklárskeho priemyslu. Hlavným cieľom dizertačnej práce je poznanie vzťahov medzi zložením, štruktúrou a vlastnosťami oxidových skiel umožňujúce vývoj metodiky na predikciu odolnosti voči korózii a zvetrávaniu. Metóda riešenia spočíva v skúmaní série skiel z pohľadu ich zloženia ako v objeme tak v povrchovej vrstve získavaného na základe termodynamického modelovania, merania povrchového napätia a analýzy povrchu vyspelými spektrálnymi metódami. Takto získané výsledky sa budú skúmať z pohľadu ich korelácie s odolnosťou skúmaných skiel vzhľadom ku korózii a zvetrávaniu.
Annotation in English: The corrosion of the tableware glass (especially in dishwashing machines in the large gastronomy) and weathering during the storage as well as during the oversea transport is from the actual point of view one of the most important questions of the glass producer’s economic competition. The main aim of the dissertation is the study of composition – structure – property relationships of oxide glasses leading to the proposal of methodology enabling the prediction of glass resistance against corrosion and weathering. The methodology is established on the set of different glasses, with differences in chemical composition of the surface as well as in the bulk. The differences are justified with respect to thermodynamic modeling, surface tension measurement and surface composition analyses by progressive spectroscopic methods. Such obtained results should be put into correlation with glass corrosion and weathering process.
