Prior to the deposition, they were heat treated to a hardness of 60 HRC. The CrAg7N coating was deposited with the magnetron-sputtering technique, using pure-Cr and Ag targets in a composite low-pressure nitrogen/argon atmosphere and at a temperature of 500 °C in the Hauzer Flexicoat 850 device. Tribological testing using a pin-on-disc apparatus was carried out at ambient and elevated temperatures: (300, 400 and 500) °C, respectively. Al2O3, 100Cr6 and CuZn balls were used as the counterparts. The wear tracks after the pin-on-disc testing were analyzed with scanning electron microscopy and a microanalysis. The experiments have shown a strong dependence of tribological parameters on the temperature. The friction coefficient of CrN-Ag against the 100Cr6 ball at ambient temperature was mi = 0.56. Tribological sliding tests of this coating system against the alumina balls indicate a decrease in the friction coefficient due to the increasing temperature. At ambient temperature mi = 0.68 and its minimum occurred at the temperature of 400 °C, mi = 0.24. This is attributed to the diffusion of Ag particles to the sliding top surface at elevated temperature. The testing against the CuZn brass ball generally gave a lower friction coefficient at ambient temperature, mi = 0.39. In contrast, the friction coefficient slightly increased with the increasing temperature and was practically constant at elevated temperatures, ranging between mi = 0.43-0.48"},{"@xml:lang":"sl","#text":"Vzorci, izdelani iz ledeburitnega orodnega jekla Vanadis 6 PM, so bili površinsko obdelani, brušeni in zrcalno polirani. Pred nanosom so bili toplotno obdelani na trdoto 60 HRC. S tehniko magnetronskega naprševanja in z uporabo tarč iz čistega Cr in Ag je bila nanesena CrAg7N-nanoprevleka v sestavljeni nizkotlačni atmosferi iz dušika in argona pri temperaturi 500 °C v napravi Hauzer Flexicoat 850. Tribološki preizkusi s preizkuševalnikom \"pin-on-disc\" so bili izvršeni pri sobni temperaturi in pri povišanih temperaturah (300, 400 in 500) °C. Krogle Al2O3, 100Cr6 in CuZn so bile uporabljene kot par. Sledi obrabe po preizkusu \"pin-on-disc\" so bile analizirane z vrstično elektronsko mikroskopijo in z mikroanalizo. Eksperimenti so pokazali močno odvisnost triboloških parametrov od temperature. Koeficient trenja CrN-Ag proti krogli 100Cr6 pri sobni temperaturi je bil mi = 0,56. Tribološki drsni preizkusi te prevleke proti kroglam Al2O3 kažejo zmanjšanje koeficienta trenja z naraščajočo temperaturo. Pri sobni temperaturi je bil mi = 0,68, minimum pa se je pojavil pri temperaturi 400 °C, mi = 0,24. To se pripisuje difuziji delcev Ag na drsno površino pri povišanih temperaturah. Preizkušanje v paru s CuZn in medeninasto kroglo je dalo na splošno nižje koeficiente trenja pri sobni temperaturi, mi = 0,39. Nasprotno pa je koeficient trenja malo narasel pri povišanju temperature in je bil pri povišanih temperaturah praktično konstanten v območju mi = 0,43-0,48"}],"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-AOGCVX48","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:DOC-AOGCVX48"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:DOC-AOGCVX48/ae2f79d2-7be0-4a71-bd33-b9bf2f3b5a24/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-AOGCVX48/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:DOC-AOGCVX48"}}}}
