Abstract
Svrha ovog diplomskog rada je ispitivanje i analiza utjecaja temperature na korozijsko ponašanje niskolegiranog čelika. U teoretskom dijelu rada opisani su korozijski procesi te osnovno objašnjene značajke kemijske i elektrokemijske korozije. Analizirani su unutrašnji i vanjski čimbenici korozije te su objašnjene vrste korozije prema obliku korozijskog razaranja metala. Razrađene su metode zaštite materijala od korozije te su opisane i obrađene dvije osnovne metode ispitivanja brzine korozije. U eksperimentalnom dijelu rada provedeno je elektrokemijsko ispitivanje utjecaja temperature na brzinu korozije niskolegiranog čelika 42CrMo4 pri različitim vrijednostima temperatura od 30 °C, 50 °C i 70 °C, uz konstantan udio NaCl otopine od 3,5 %. Temeljem eksperimenta utvrđeno je da niskolegirani čelik 42CrMo4 ne spada u korozijski postojane materijale te da povećanjem temperature elektrolita brže dolazi do korozijske reakcije. Porastom temperature sa 30 °C na 70 °C brzina korozije porasla je za 214,98 %.
Abstract (english)
The purpose of this thesis is examination and analysis of the influence of temperature on the corrosion behavior of low-alloy steel. In the theoretical part of the work, corrosion processes and basic features of chemical and electrochemical corrosion are described and explained. The internal and external factors of corrosion are analyzed and the types of corrosion are explained according to the form of corrosion destruction of metals. Methods of protecting materials from corrosion have been elaborated, and two basic methods of corrosion rate testing have been described and processed. In the experimental part of the work, an electrochemical test of the effect of temperature on the corrosion rate of low-alloy steel 42CrMo4 was carried out at different temperature values of 30 °C, 50 °C and 70 °C, with a constant proportion of NaCl solution of 3,5 %. Based on the conducted experiments, it was concluded that low-alloy steel 42CrMo4 cannot be classified as corrosion-resistant material and that the rate of corrosion reaction is conditioned by the increase of temperature of the electrolyte. The increase of temperature from 30 °C to 70 °C increased the rate of corrosion reaction for 214,98 %.
