In this study, aluminium composites were produced with 10 % and 20 % silicon-carbide and ferroboron reinforcements and (0, 0.5, 1 and 1.5) % graphite additions using powder metallurgy. The effects of the reinforcement type, the amount and the graphite content on the wear resistance were investigated. When compared with the unreinforced aluminium sample, it was clear that the increasing reinforcement increased the wear resistance. It was determined that the increasing graphite content negatively affects the wear resistance. The sample including 20 % ferroboron and 0 % graphite showed the minimum wear rateSilicijev karbid se pogosto uporablja za ojačanje pri proizvodnji aluminijevih kompozitov iz prahov. V tej študiji so bili aluminijevi kompoziti izdelani po metalurgiji prahov, utrjeni z 10 %, 20 % silicijevega karbida, fero-bora in dodatkom (0, 0,5, 1 in 1,5) % grafita. Raziskani so bili vplivi vrste ojačitve, količine ojačitve in količine grafita na odpornost proti obrabi. V primerjavi z neutrjenimi vzorci aluminija je razvidno, da se odpornost proti obrabi povečuje z večanjem utrjevanja. Ugotovljeno je, da povečanje količine grafita negativno vpliva na odpornost proti obrabi. Najmanjšo stopnjo obrabe je pokazal vzorec, ki je vseboval 20 % fero-bora in bil brez grafitaTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaInštitut za kovinske materiale in tehnologije
