A tribological evaluation of TiN, TiB2, TaC and diamond like coating (DLC) coatings deposited on cold-worked tool steel was carried out in a load-scanning test rig and compared to the behaviour of different uncoated forming tool steels. The special test configuration, where austenitic stainless steel was used as the counter-material, makes it possible to gradually increase the normal load during forward sliding strokes, and to correspondingly decrease the load during reversed ones. In this investigation, the load range was 100 to 1300 N (contact pressure from 1 to 5 GPa). The experimental results indicate that theintroduction of an appropriate hard coating will lead to an improved wear resistance and a longer lifetime for the forming tool. Furthermore, by using hard low-friction coatings excellent anti-sticking properties can be obtained"},{"@xml:lang":"sl","#text":"Namen predstavljenega prispevka je bil raziskati moznosti uporabe trdih prevlek fizikalno nanesenih v vakuumu (FNV - PVD) na orodjih za hladno preoblikovanje. V raziskavo so bile vključene prevleke TiN, TiB2, TaC in diamantu podobna prevleka na podlagi trdega ogljika (DPP), katerih tribološke lastnosti smo primerjali z različnimi orodnimi jekli za delo v hladnem jeklarne Uddeholm Tooling iz Švedske. Tribološke lastnosti materialov, vključenih v raziskavo, smo določili na preizkuševalisču, katerega izoblikovanost omogoča izmenično in zvezno povečevanje ter zmanjsevanje obremenitve med drsenjem. Obremenitev je bila v območju med 100 in 1300 N (kontaktni tlak med 1 GPa in 5 GPa), kot protimaterial pa smo uporabili avstenitno jeklo. Rezultati raziskave kazejo, da uporaba ustrezne prevleke privede do povečane obrabne obstojnosti orodja ter do precejšnjega zmanjšanja pojava lepljenja obdelovanega materiala na površino orodja"}],"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-Z5ING7I6","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:doc-Z5ING7I6"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:doc-Z5ING7I6/ef28ce9f-4c70-45aa-9dd6-b1d618b9aec7/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":"Univerza v Ljubljani, Fakulteta za strojništvo"},"edm:object":{"@rdf:resource":"http://www.dlib.si/streamdb/URN:NBN:SI:doc-Z5ING7I6/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:doc-Z5ING7I6"}}}}
