Recently work has been done on Cr-C hard coatings and some industrial applications were reported, in particular, the protection of tools for aluminium die-casting. However, information about the ternary Cr(C,N) hard coataings is scarce. We prepared several Cr(C,N) hard coatings with different C:N ratios by varying the ?$N_2$? and ?$C_2H_2$? flow. Stoichiometric, as well as nonstoichiometric Cr-N and Cr-C coatings were prepared for comparison. The coatings were deposited by evaporation in a thermionic arc ion plating BAI730M (Balzers) apparataus. Polished tool steel disks, silicon wafers and polished alumina ceramics were used as substrates. Oxidation of the coatings was carried out by heating the samples at 750-900°C in an oxygen atmosphere while measuring the weight gain and the thickness increase. The depth profiles of the samples, oxidized at various temperatures,were measured by Auger Electron Spectrometer (AES). Microhardness, adhesion and surface roughness were also measured. We investigated the influence of the ?$N_2$? and ?$C_2H_2$? partial pressures on the above mentioned physical and chemical properties. The results show that Cr-C coatings do have the potential for industrial application"},{"@xml:lang":"sl","#text":"Raziskave Cr-N trdih prevlek potekajo že več kot 10 let in so se uspešno uveljavile v industriji. Zadnjih nekaj let se raziskuje tudi Cr-C trde prevleke in prišlo je že do prvih industrijskih aplikacij, konkretno za prekrivanje orodij za tlačno litje aluminija. Toda informacij o ternarni Cr(C,N) trdi preavleki je malo. Pripravili smo več Cr(C,N) trdih preavlek z različnim atomskim razmerjem C:N tako, da smo spreminjali pretok ?$N_2$? in ?$C_2H_2$?. Za primerjavo smo pripravili tudi stehiometrične in nestehiometrične Cr-N in Cr-C prevleke. Prevleke smo pripravili z naparevanjem v termionskem sistemu BAI730M (Balzers) za ionsko prekrivanje. Za podlage smo uporabili polirane ploščice iz orodnega jekla, silicijeve rezine in polirano aluminij-oksidno keramiko. Vzorce smo oksidirali tako, da smo jih segrevali pri temperaturah 750-900°C v kisikovi atmosferi in merili prirastek mase in debeline. Globinski profil vzorcev, ki smo jih oksidirali pri različnih temperaturah, smo izmerili z Augerjevim elektronskim spektrometrom (AES). Izmerili smo tudi mikrotrdoto, adhezijo in hrapavost površine. Študirali smo vpliv delnega tlaka ?$N_2$? in ?$C_2H_2$? na zgoraj omenjene fizikalne in kemijske lastnosti. Rezultati lažejo, da so Cr-C prevleke potencialno uporabne v industrijske namene"}],"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-58E2WNX7","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:DOC-58E2WNX7"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:DOC-58E2WNX7/8950f923-8f82-4fb2-bff7-15b999210e70/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-58E2WNX7/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:DOC-58E2WNX7"}}}}
