Pri različnih aplikacijah so pogosto izpostavljene korozijskemu okolju. Trde prevleke so kemijsko inertne in same po sebi korozijsko obstojne. Med njihovo pripravo pa nastane v njih veliko defektov (kraterji, \"pinholi\"). Nekateri od njih segajo do podlage. Na teh mestih pride do jamičaste korozije, kar pa je z vidika uporabe neželeno. TiAlN-prevleko smo nanesli na podlago orodnega jekla D2 po postopku naprševanja z neuravnoteženim magnetronskim izvirom. Defekte, ki so nastali med pripravo plasti, smo preučili po korozijskem preizkusu. Za analizo smo uporabili dve metodi. Vrstični elektronski mikroskop(SEM), s katerim smo pridobili splošni pregled prevleke, kot tudi 2D-karakterizacijo defektov. Kot drugo metodo smo uporabili fokusiran ionski curek, ki je integriran v klasični SEM, s katerim smo izvedli serijo rezov izbranih defektov za njihovo 3D-karakterizacijo. V delu smo poskušali na specifičnih mestih ugotoviti mehanizem nastanka defektov in ugotovljali, ali povzročajo jamičasto korozijo"},{"@xml:lang":"sl","#text":"PVD hard coatings are continuously gaining their importance in different fields of applications. In industrial use, they are often exposed to corrosive environments. Hard coatings possess inherently good corrosion resistance, but the substrate-hard coating systems may suffer from a severe corrosion attack due to the defects (craters, pin holes) in the coatings. On the sites, where defects extend through the coating, pitting corrosion can take place. These sites are drawbacks in the applications of hard coating. A PVD TiAlN hard coating was prepared on cold-work, tool-steel (AISI D2) substrates by sputtering using unbalanced magnetron sources. The growth defects incorporated into the coating were studied after the deposition and corrosion experiments. We used two methods: (1) scanning electron microscopy (SEM) for general overview of the coating topography and 2D-characterization of defects, and (2) scanning electron microscopy with a focused ion beam (SEM-FIB) for making serial cross-sections through the selected defects in order to provide images for a 3D-reconstruction of defects. In this work we tried to investigate the formation of a defect at a specific location and findout whether the selected defect causes pitting corrosion"}],"edm:type":"TEXT","dc:type":[{"@xml:lang":"sl","#text":"znanstveno časopisje"},{"@xml:lang":"en","#text":"journals"},{"@rdf:resource":"http://www.wikidata.org/entity/Q361785"}]},"ore:Aggregation":{"@rdf:about":"http://www.dlib.si/?URN=URN:NBN:SI:DOC-J9G7VALH","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:DOC-J9G7VALH"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:DOC-J9G7VALH/8d76f566-cadc-4a56-a166-ecbd8c97b563/PDF"},"edm:rights":{"@rdf:resource":"http://rightsstatements.org/vocab/InC/1.0/"},"edm:provider":"Slovenian National E-content Aggregator","edm:intermediateProvider":{"@xml:lang":"en","#text":"National and University Library of Slovenia"},"edm:dataProvider":{"@xml:lang":"sl","#text":"Inštitut za kovinske materiale in tehnologije"},"edm:object":{"@rdf:resource":"http://www.dlib.si/streamdb/URN:NBN:SI:DOC-J9G7VALH/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:DOC-J9G7VALH"}}}}
