However, these applications are still restricted by the relatively poor surface resistance of these materials. To overcome the inherent drawbacks a useful solution is to deposit a protective coating on the magnesium alloys. The sol-gel process is an effective method for fabricating oxide films on a magnesium alloy in order to produce a higher corrosion resistance. The objective of this study is to comparatively investigate the process and properties of repeated sol-gel oxide (ZrO2, Al2O3) coatings. The coatings were characterized by SEM, XRD, ellipsometry and the effects of the process on their properties were comparatively analysedMagnezij in njegove zlitine se uporabljajo v vrsti industrij zaradi visoke specifične trdnosti (razmerje trdnost - gostota). Vendar pa je industrijska uporaba omejena zaradi njihove slabe odpornosti površine. Da bi to pomanjkljivost odpravili, je uporabna rešitev varovalni nanos na površini magnezijevih zlitin. Sol-gel postopek je učinkovita metoda za izdelavo oksidnih tankih plasti na magnezijevi zlitini za povečanje njihove korozijske obstojnosti. Namen te študije je primerjava postopka in ugotavljanje lastnosti ponavljajočih se sol-gel nanosov ZrO2 in Al2O3. Nanosi so bili ovrednoteni s SEM, XRD in elipsometrijo, izvršena pa je bila tudi primerjava vpliva procesa na njihove lastnostiTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaInštitut za kovinske materiale in tehnologije
