Hardness tests were also carried out. Graphite was used as a solid lubricant since it is a soft, slippery and greyish-black substance. Because of the cleavage (crystal) loose interlamellar coupling, graphite has good lubricating properties. A comparative analysis was made on the hardness and wear behavior of AA6061, AA6061-B4C composite and AA6061-B4C-Gr hybrid composite. Boron carbide is known as a robust material having a high hardness. Worn-out surfaces of the wear specimens after the wear tests were examined with a scanning electron microscope to study the morphology of the worn surfaces. Energy dispersive spectroscopy (EDS) was employed to identify the oxides formed on the worn surfaces of the AA6061-B4C and AA6061-B4C-Gr composites after the wear test. It was found that a mutual transfer of the material between the wearing Al-alloy and the steel counterface occurred as the load increased. Oxidative wear occurred at low applied loads and a high velocity, whereas delamination and adhesive wear occurred at a high load and high sliding velocity"},{"@xml:lang":"sl","#text":"Preiskovano je bilo vedenje AA6061, AA6061-B4C-kompozita in hibridnega kompozita AA6061-B4C-Gr pri suhem drsenju z uporabo naprave \"pin on disc\". Kot trdno mazivo je bil uporabljen grafit, ki je mehka, spolzka in sivo-črna snov. Zaradi cepljive šibke medlamelarne povezave (v kristalu) ima grafit dobre mazalne lastnosti. Izvršene so bile analize primerjave trdote in vedenja pri obrabi AA6061, AA6061-B4C-kompozita in hibridnega kompozita AA6061-B4C-Gr. Borov karbid je poznan kot zdržljiv material z veliko trdoto. Po preizkusu obrabe je bila z elektronskim vrstičnim mikroskopom izvršena preiskava morfologije obrabljene površine vzorcev, da bi ugotovili nastale okside na obrabljeni površini kompozitov AA6061-B4C in AA6061-B4C-Gr. Ugotovljeno je bilo, da se pri naraščanju obremenitve pojavi vzajemen prenos materiala med Al-zlitino, ki se obrablja, in jeklom. Oksidativna obraba se je pojavila pri majhnih obremenitvah in velikih hitrostih, medtem ko se je obraba zaradi delaminacije in adhezije pojavila pri velikih obremenitvah in veliki hitrosti drsenja"}],"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-NNKUQ5Y0","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:DOC-NNKUQ5Y0"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:DOC-NNKUQ5Y0/768525bb-87bf-41c4-a5a5-3c5387506524/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-NNKUQ5Y0/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:DOC-NNKUQ5Y0"}}}}
