Abstract
U ovom diplomskom radu opisani su nehrđajući čelici i njihova korozijska svojstva, a poseban naglasak stavljen je na koroziju zavarenih spojeva. Opisani su korozijski procesi do kojih može doći u zavarenim spojevima te načini kako se oni mogu spriječiti ili barem umanjiti. Posebno su opisani superaustenitni nehrđajući čelici, njihove karakteristike te njihova korozijska svojstva i najčešći problemi koji se kod tih čelika mogu pojaviti. Opisana su dva često korištena superaustenitna čelika oznaka EN 1.4539 (AISI 904L) i EN 1.4547 (254 SMO). U eksperimentalnom dijelu rada, uzorci ova dva superaustenitna nehrđajuća čelika te dva austenitna nehrđajuća čelika oznaka EN 1.4301 (AISI 304) i EN 1.4404 (AISI 316L) ispitivani su na rupičastu koroziju te su uspoređeni rezultati ispitivanja. Također su ispitivani uzorci sa zavarenim spojem te uzorci osnovnog materijala i provedena je analiza rezultata dobivenih korozijskim ispitivanjem te su izneseni zaključci.
Abstract (english)
In this thesis, stainless steels and their corrosion characteristics are described, but special emphasis is given to corrosion of welded joints. Corrosion processes that can occur in welded joints and solutions for reducing or preventing them are described. Superaustenitic stainless steels are described in their own chapter, as well as their characteristics, corrosion behavior and the most common corrosion problems that can occur in these steels. Two mostly used superaustenitic steels are described, EN 1.4539 (AISI 904L) and EN 1.4547 (254 SMO). In the experimental part of the thesis, the two superaustenitic stainless steels and two austenitic stainless steels, EN 1.4301 (AISI 304) and EN 1.4404 (AISI 316L) are tested for pitting corrosion and the test results are compared. Also, samples with welded joints and samples of base metal are both tested, result analysis is made and conclusions are introduced.
