Abstract
U prvom dijelu rada dan je teorijski pregled o konstrukcijskim čelicima s naglaskom na čelike za poboljšavanje. Opisana je njihova podjela i primjena. U teorijski dio rada uključene su i teorijske osnove o koroziji, a detaljnije je opisana kemijska korozija i korozija uzrokovana visokotemperaturnim zagrijavanjem. U eksperimentalnom dijelu rada korišteni su uzorci čelika za poboljšavanje HRN Č.4732, koji su u različitoj duljini trajanja bili podvrgnuti visokotemperaturnom zagrijavanju. Eksperiment je osmišljen u svrhu praćenja stvaranja oksida u ovisnosti o vremenu zagrijavanja. Uzorcima čelika izmjeren je prirast mase i debljina oksidnog sloja nakon zagrijavanja, pri čemu je ustanovljeno da se prirast mase povećava s vremenom zagrijavanja u peći. Napravljena je i analiza mikrostrukture čelika u nagriženom stanju, gdje se uočila pojava razugljičavanja po rubovima uzoraka.
Abstract (english)
First part consists of theoretical overview of structural steels with an emphasis on quenching and tempering steels with description of their use and classification. Followed by theoretical basis about corrosion with detailed description of chemical corrosion and corrosion caused by high temperature heating. In the experimental part of the thesis the samples of quenching and tempering steels HRN Č.4732 were used, which were subjected to high temperature heating. The experiment was design to monitor the formation of oxides in relation to the heating time. After the heating, the weight gain and the thickness of the oxide layer were measured. It was found out that the weight gain increases with the heating time in the furnace. The analysis of the microstructure of steel in etched condition was performed, where the appearance of the decarburization on the edges of the sample was observed.
