Lasersko legiranje in navarjanje tankih površinskih slojev : magistrsko delo

Slabe, Janez Marko

Obratovalno dobo obremenjenih strojnih delov in vitalnih delov orodij lahko uspešno podaljšujemo s sistematičnim vzdrževanjem in pravočasno reparaturo poškodovane površine. Dokazano je, da lahko z ... doslednim vzdrževanjem delov orodij znatno zmanjšamo delež stroška za orodje v ceni izdelka. Zelo ekonomično je izdelati določene obremenjene strojne dele iz cenejšega in bolj žilavega konstrukcijskega jekla in nato na obremenjene površine navariti sloj obrabno odporne zlitine. Pri tem je volumski delež navarjenega sloja glede na celotni volumen orodja ali strojnega dela običajno zelo nizek. V delu so predstavljeni rezultati raziskav navarjanja maraging jekla 1.2799 in oplemenitenja površine navadnega konstrukcijskega jekla St 44-3 z Ni-Co-Mo zlitinami sorodnimi maraging jeklom z uporabo laserskega navarjanja oz. oblaganja in elektro obločnega navarjanja pod praškom. Rezultati zajemajo mikrostrukturno analizo na optičnem in elektronskem mikroskopu, spektrografsko mikrokemijsko analizo in kemijsko analizo navarjenih oz. obloženih slojev, podprto z analizo mikrotrdote in zaostalih napetosti.
