Abstract
Ob pojavu razpok na nekonvencionalno izdelanem gravurnem vložku na orodju za tlačno litje aluminija, je bilo treba pregledati literaturo in analizirati možne mehanizme, ki vplivajo na iniciacijo razpoke, propagacijo razpoke in lom vložka. Da bi ugotovil poglavitne vzroke za odpoved gravurnega vložka, sem pregledal literaturo o poškodbenih mehanizmih prisotnih v tlačnem litju, pojavu razpok, mehanskimi lastnosti zaradi izdelovalnega postopka SLM in postopkih reparaturnega varjenja. Za zagotovitev ustreznejšega reparaturnega postopka sem podjetju predlagal izboljšavo, z vpeljavo hibridnega procesa. Predlagana kombinacija odrezavanja in aditivne tehnologije DED, bi lahko zagotovila ekonomsko učinkovitejši vzdrževalno - reparaturni postopek.

Secondary title: |
Analysis of crack occurance on an aluminium die casting tool |
Secondary abstract: |
Due to crack occurrence on an unconventionally made insert, produced for high pressure die casting machine, it was necessary to review the literature and analyze possible mechanisms influencing crack initiation, crack propagation, and insert fracture. To determine the main causes of insert failure, I reviewed the literature on the damage mechanisms present in die casting, the occurrence of cracks, mechanical properties due to the SLM fabrication process, and repair welding processes. To ensure a more appropriate repair process, I proposed an improvement to the company, by introducing a hybrid process. The proposed combination of cutting and additive technology DED, could provide a more cost - effective maintenance - repair process. |
