The modified samples were characterized before and after the wear testing using metallographic, SEM-microscope and microhardness techniques. The test results indicate that the wear resistance of the AISI 4140 steel can be improved by means of electrolytic-plasma technology (EPT). The wear resistance increases with an increased modified-layer hardness due to a transformation to the martensitic structurePreučevane so bile obrabne lastnosti pri suhem drsenju in različnih parametrih z elektrolitsko plazmo obdelane površine jekla AISI 4140. Modificirani vzorci so bili karakterizirani pred preizkusom obrabe in po njem z uporabo metalografije, z vrstičnim elektronskim mikroskopom (SEM) in meritvijo trdote. Rezultati so pokazali, da se obrabna odpornost jekla AISI 4140 lahko poveča s tehnologijo elektrolitske plazme (EPT). Obrabna odpornost se povečuje s povišanjem trdote modificirane plasti zaradi pretvorbe v martenzitno mikrostrukturoTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaInštitut za kovinske materiale in tehnologije
