Karakterizacija oblikovno obločno navarjene aluminijeve zlitine AlSi5 : diplomsko delo Visokošolskega strokovnega študijskega programa I. stopnje Strojništvo - Projektno aplikativni programIvančič, Tomaž, strojnikOblikovno obločno navarjanje z žico (angl. WAAM – Wire and Arc Additive manufacturing) je ena izmed najnaprednejših tehnologij, ki poteka po principu navarjanja dodajnega materiala plast za plastjo. ... Značilna prednost te tehnike je, da lahko proizvajamo velike in masivne izdelke z nizkimi stroški in kratkim časom izdelave. Zaradi novosti v tehnologiji (počasi se tehnologija že uveljavlja v industriji, predvsem v letalski), smo se odločili, da raziščemo karakteristike pri navarjanju aluminija. Aluminij in njegove zlitine so pogosto v uporabi zaradi nizke mase in gostote, dobre korozijske odpornosti, toplotne in električne prevodnosti, relativno dobre trdnosti ter duktilnosti. Zaradi aluminijeve težavnosti pri varjenju smo varili po programu CMT+PULSE (angl. Cold Metal Transfer) ter poskusili navariti tanke in široke stene. Po končanem postopku pa smo jih preizkusili na treh različnih testih; nateznem, žilavostnem in upogibnem, prav tako smo pregledali tudi mikostrukturo. Ugotovili smo, da je pri širokih stenah pojavnost poroznosti tudi do 60 % večja (razmerje 6 proti 1 v količini mehurčkov). Izkazalo se je, da ima vertikalna orientacija vzorca za 10° večji upogibni kot pri porušitvi nasproti horizontalni (35° proti 25° v povprečju). Pri ostalih preizkusih bistvenih razlik v orientaciji vzorcev ni bilo.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [T.
