Abstract
U diplomskom radu naslova „Utjecaj inhibitora na korozijsko ponašanje niskolegiranog čelika u 3,5%-tnoj otopini NaCl“ analiziran je utjecaj tri različite vrste inhibitora na niskolegirani čelik oznake 51CrV4 u 3,5%-tnoj otopini NaCl. Diplomski rad se sastoji iz dva dijela: teorijski i eksperimentalni. Teorijski dio rada općenito objašnjava korozijske procese, a opisane su i vrste korozije prema obliku korozijskog razaranja. Također su razrađene metode zaštite materijala od korozije, dok je posebna pažnja posvećena zaštiti od korozije primjenom inhibitora. U eksperimentalnom dijelu rada provedeno je elektrokemijsko ispitivanje korozije niskolegiranog čelika 51CrV4 u 3,5%-tnoj otopini NaCl-a primjenom tri inhibitora: glicerin, natrijev tiosulfat pentahidrat, natrijev hidrogenkarbonat. Temeljem eksperimenta utvrđeno je da je natrijev tiosulfat pentahidrat definitivno inhibitor, dok glicerin nije inhibitor te čak povećava brzinu korozije. Zbog određenog izgleda Tafelove krivulje prilikom korištenja natrijevog hidrogenkarbonata, nisu dobiveni podaci o korozijskom ponašanju ispitnog čelika.
Abstract (english)
In graduation thesis titled „Effect of Inhibitors on the Corrosion Behavior of Low-alloy Steel in a 3,5% NaCl solution analyzed the influence of three different types of inhibitors on low-alloy steel 51CrV4 in a 3,5% NaCl solution. The thesis consist of two parts: theoretical and experimental. The theoretical part of the work explains corrosion processes in general, and the types of corrosion according to the form of corrosion destruction are also described. Methods of protecting materials from corrosion have also been elaborated, while special attention has been paid to corrosion protection using inhibitors. In the experimental part, an electrochemical test of low-alloy steel 51CrV4 in a 3,5% NaCl solution was performed using three inhibitors: glycerin, sodium thiosulfate pentahydrate, sodium bicarbonate. Based on the experiment, it was determined that sodium thiosulfate pentahydrate is definitely an inhibitor, while glycerin is not an inhibitor and even increases the rate of corossion. Due to the certain appearance of the Tafel curve when using sodium hydrogen carbonate, no data were obtained on the corrosion behavior of the test steel.
