Abstract
Cilj rada je bio analizirati mikrostrukturu zavarenog spoja Corten čelika oznake S355J0WP (osnovni materijal, zonu utjecaja topline i metal zavara). Također je analiziran i uspoređen oksidni sloj na osnovnom materijalu i u području zavarenog spoja na uzorcima koji su kroz 200 dana bili izloženi djelovanju atmosfere u ruralnom, industrijskom i morskom okruženju. U teorijskom dijelu rada opisani su opći konstrukcijski čelici, te oblici i vrste korozije. Poseban naglasak stavljen je na čelike s povišenom otpornošću na atmosfersku koroziju. Opisane su vrste Corten čelika, stvaranje oksidnog sloja na površini, postupci zavarivanja te područja primjene. U eksperimentalnom dijelu rada prikazani su rezultati dobiveni vizualnim pregledom korodiranih površina, rezultati analize kemijskog sastava, analize mikrostrukture, EDS analize i rezultati statičkog vlačnog ispitivanja. Pokazalo se da vrsta atmosfere ima vrlo veliki utjecaj na intenzitet korozije i kvalitetu nastalih oksidnih slojeva na površini Corten čelika. Najtanji oksidni sloj i najravnomjernija prekrivenost površine korozijskim produktima postignuta je u ruralnoj atmosferi, a najmanja homogenost i najveća dubina korozije u morskoj atmosferi.
Abstract (english)
The aim of the paper was to analyze the microstructure of the welded joint of the Corten steel grade S355J0WP (base metal, heat-affected zone and weld metal). The oxid layer on the base material and oxid layer in the weld area on samples that were exposed to atmospheric influence in the rural, industrial and marine environment for 200 days was also analyzed and compared. Theoretical part of the paper describes general structural steels, and forms and types of corrosion. Special emphasis was placed on steels with increased resistance to atmospheric corrosion. In this part, types of Corten steel, the formation of an oxide layer on the surface, welding processes and application areas were described. In the experimental part, the results obtained by visual inspection of corroded surfaces, results of chemical composition analysis, microstructure analysis, EDS analysis and static tensile test results are presented. It has been shown that the type of atmosphere has a great influence on the corrosion intensity and the quality of the oxide layers formed on the Corten steel surface. The thinnest oxide layer and the most uniform surface coverage of corrosion products was achieved in the rural atmosphere, with the lowest homogeneity and the greatest depth of corrosion in the marine atmosphere.
