Abstract (Croatian)

Izmjenjivači topline toplinski su aparati čija je svrha prijenos topline s jednog fluida na drugi. Korozija kod izmjenjivača može uzrokovati štetne ili katastrofalne posljedice stoga se provodi navarivanje, nanošenje dodatnog materijala na površinu osnovnog materijala uobičajenim postupcima zavarivanja, a sa svrhom dobivanja korozijski postojanih površina. U prvom dijelu eksperimenta optimizirana je tehnologija MAG navarivanja čelikom AISI 410 na osnovnom materijalu SA 516 Gr 60. Zatim je provedeno navarivanje sukladno normi HR\N E\N ISO 15614-7 te su se ispitni uzorci podvrgli postupcima ispitivanja zahtijevanim tom istom normom. Sukladno rezultatima ispitivanja zahtijevana je toplinska obrada nakon čije provedbe su ispunjeni svi zahtjevi.

Abstract

Heat exchangers are heat transfer devices whose purpose is to exchange heat between one to another fluid. In heat exchangers corrosion can cause harmful or disastrous consequences, therefore, cladding is carried out with conventional welding processes to provide corrosion resistance surface. In the first part of the experiment optimized was MAG cladding technology with high alloyed steel AISI 410 on basic material SA 516 Gr 60. Afterwards, cladding was carried out in accordance to HRN EN ISO 51614-7 and test samples were subjected to the test procedures required by the same standard. In accordance with the results, post weld heat treatment was required after whose implementation all requirements were satisfied.
