Abstract
U ovom završnom radu određena je postojanost Corten čelika u destiliranoj vodi, kiseloj kiši i morskoj vodi preko vizualne kontrole površine, gravimetrijske analize i elektrokemijske impedancijske spektroskopije. U teorijskom dijelu rada opisano je djelovanje korozije na niskolegirane čelike te njihova podjela. Poseban naglasak stavljen je na Corten čelik oznake S355J0WP s povišenom otpornošću na atmosfersku koroziju, njegove vrste, primjena i način stvaranja oksidnog sloja. Opisan je i postupak elektrokemijske impedancijske spektroskopije. U eksperimentalnom dijelu rada prikazani su rezultati dobiveni vizualnim pregledom korodiranih površina, analize rezultata gravimetrije, elektrokemijske impedancijske spektroskopije i analize mikrostrukture. Uzorak Corten čelika najviše je korodirao u morskom mediju. Kod njega je izmjeren mali gubitak mase, površina uzorka nije ravnomjerno korodirala te je postala reaktivnija, a ne otpornija na korozijsko djelovanje.
Abstract (english)
In this paper, the stability of Corten steel in distilled water, acid rain and seawater was determined through visual surface control, gravimetric analysis, and electrochemical impedance spectroscopy. The theoretical part of the paper describes the effect of corrosion on low alloy steels and their division. Special emphasis is placed on Corten steel grade S355J0WP with increased resistance to atmospheric corrosion, its types, applications and formation of oxide layer. The electrochemical impedance spectroscopy procedure is also described. In the experimental part, the results obtained by visual inspection of corroded surfaces, results of gravimetry, analysis of electrochemical impedance spectroscopy, and microstructure analysis are presented. The Corten steel sample corroded the most in the marine environment. It measured a small loss of mass, the surface of the sample did not corrode uniformly and it became more reactive rather than more resistant to corrosion.
