The multilayer structure consists of a nitrided layer on a steel substrate and a hard coating deposited by Physical Vapor Deposition and Ion Beam Assisted Deposition. In the present investigation the subsequent ion implantation was provided by N2sup+ ions. This paper describes the use of the nano-indentation technique for a determination of the hardness and elastic modulus. The results are analyzed in terms of load-displacement curves, hardness, Young's modulus, unloading stiffness and elastic recovery. The analysis of the indents was performed with an Atomic Force Microscope. The analyzed AE signal was obtained by a scratch test designed for adherence evaluation. The coating is often in tensile stress with greater microhardness. The stress determination follows the conventional sinsup2 psi method, using an X-ray diffractometer. A variety of analytic techniques were used for the characterization, such as a scratch test, calo test, SEM, AFM, XRD and EDAX for engineering applications. The experimental results indicated that the mechanical hardness is elevated by the penetration of nitrogen, whereas the Young's modulus is significantly elevated"},{"@xml:lang":"sl","#text":"Mehanske lastnosti novih prekritij na podlagi večplastne strukture so bile raziskane v merilu nanometra. Večplastna struktura sestoji iz nitridne plasti na podlagi iz jekla, trdo prekritje pa je naneseno s fizikalnim nanosom par in nanosom z ionskim curkom. Uporabljena je tudi ionska implantacija z Nspodaj2-ioni. Opisana je uporaba nanoindentacije za določitev trdote in elastičnega modula. Rezultati so analizirani z upoštevanjem odvisnosti obremenitev - deformacija, trdote, Youngovega modula, razbremenitvene togosti in elastične poprave. Analiza indentacij je bila izvršena z mikroskopom na atomsko silo. Analizirani AE-signal je bil dobljen s preizkusom razenja, namenjen za določanje oprijetosti. V prekritju so pogosto natezne napetosti, ima pa tudi veliko mikrotrdoto. Določitev napetosti je bila izvršena z metodo sinna2 psi in uporabo rentgenskega difraktometra. Za karakerizacijo je bila uporabljana vrsta analitičnih tehnik, kot so preizkus razenja, calo-preizkus, SEM, AFM, XRD in EDAX za inženirsko uporabo. Eksperimentalni rezultati kažejo, da se mehanska trdota povečuje s penetracijo dušika, pri čemer je Youngov modul pomembno povečan"}],"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-WCKWVXKO","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:DOC-WCKWVXKO"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:DOC-WCKWVXKO/0f798c8e-1026-4ddc-a4e7-ae69cf8ed8c0/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-WCKWVXKO/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:DOC-WCKWVXKO"}}}}
