Abstract
Korozija negativno utječe na industrijsku i drugu opremu i proizvode na način da skraćuje njihov vijek trajanja te zbog toga nastaju visoki troškovi, a moguće su i štete i nesreće. U ovom radu nastoji se pokazati kako je problemu korozije potrebno pristupiti adekvatnim razumijevanjem korozijskog procesa te utjecaja različitih faktora na brzinu i tok korozije kod niskolegiranih čelika Diplomski rad je sastavljen iz dva dijela: teoretskog pregleda tematike korozije s naglaskom na utjecaj... More medija na koroziju te na koroziju kod niskolegiranog čelika i eksperimentalnog rada. U uvodnom teoretskom dijelu predstavljene su vrste korozije prema mehanizmima djelovanja, prema oblicima razaranja s posebnim naglaskom na čimbenicima i utjecaju medija na koroziju te zaštitu materijala od korozije. U nastavku su također obrađene karakteristike korozije i zaštite od korozije za niskolegirane čelike s obzirom da se u eksperimentalnom dijelu koristi taj materijal za elektrokemijsko ispitivanje korozijskih reakcija. U eksperimentalnom dijelu rada provedena su elektrokemijsko ispitivanje brzine korozijske reakcije kod niskolegiranog čelika sa svrhom analize utjecaja medija (vodene otopine NaCl) različitih koncentracija i temperatura na korozijsko ponašanje specifičnog čelika 42CrMo4. Prema dobivenim rezultatima moguće je zaključiti da koncentracija, a naročito temperatura medija utječe na brzinu i tok korozijske reakcije kod ispitivanih uzoraka niskolegiranog čelika. Less
Abstract (english)
Corrosion negatively affects industrial and other equipment and products in a way that shortens their life span and resulting in high costs and possible damage and accidents. This paper seeks to show how the problem of corrosion needs to be approached by an adequate understanding of the corrosion process and the influence of various factors on the speed and flow of corrosion in lowalloy steels. The present thesis consists of two parts: theoretical review of the topic of corrosion with... More emphasis on the influence of medium on corrosion and corrosion in low-alloy steels and experimental work. The theoretical part presents types of corrosion according to the corrosion mechanisms and forms of destruction with special emphasis on the corrosion factors and influence of the medium on corrosion and variaty of the corrosion protection modalities. The corrosion and corrosion protection mechanisms for low-alloy steels are also discussed, since this material is used in the experimental part for electrochemical testing of corrosion reactions. In the experimental part of the thesis, the electrochemical testing of the corrosion reaction rate in low-alloy steels was performed to analyze the influence of media (NaCl solution) of different concentrations and temperatures on the corrosion behavior of specific steel 42CrMo4. According to the obtained results, it is possible to conclude that the concentration, and especially the temperature of the medium, affects the speed and flow of the corrosion reaction in the tested samples of low - alloy steel.
