However, the deposition of thin films onto the nitrided surface is associated with problems that are not yet solved. To clarify the problem of the adhesion and mechanical properties of the system substrate/coating it is necessary to prepare the substrate with well-defined microstructural parameters. The Vanadis 6 PM ledeburitic steel was chosen as a substrate for surface processing. It was austenitised, quenched and double tempered to a desired hardness of HRC = (57-58). Some specimens were also sub-zero treated in order to improve the transformation of austenite to martensite. The microstructure of the heat-processed steel was examined using optical microscopy and scanning electron microscopy. The resistance to nucleation of fracture was assessed with the three-point bending-strength test and the fracture surfaces were subjected to a fractographic analysis"},{"@xml:lang":"sl","#text":"Dupleksno pokritje visokolegiranih orodnih jekel je nova in obetajoča tehnologija za povečanje obrabne obstojnosti in dobe uporabnosti orodij.

Za razlago problema adhezije in mehanskih lastnosti sistema podlaga-pokritje je treba pripraviti podlago z dobro opredeljenimi parametri mikrostrukture. Jeklo Vanadis 6 PM je bilo izbrano za podlago za nadaljevanje procesiranja. Bilo je avstenitizirano, kaljeno in dvakrat popuščeno na želeno trdoto HRC = (57-58). Nekateri preizkušanci so bili tudi podhlajeni zaradi povečanja obsega premene avstenita v martenzit. Mikrostruktura je bila preiskana z optično in vrstično elektronsko mikroskopijo. Odpornost proti začetku razpoke je bila preverjena s tritočkovnim upogibom, površina prelomov pa fraktografsko preiskana"}],"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-3ZWXGCDQ","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:DOC-3ZWXGCDQ"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:DOC-3ZWXGCDQ/e94a6435-f309-495c-b34f-a58e246b6af4/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-3ZWXGCDQ/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:DOC-3ZWXGCDQ"}}}}
