Abstract
Ovaj rad bavi se nitriranjem čelika tipa 20MnCr5 pomoću ekološki prihvatljive solne kupelji na bazi KNO₃. Rad je podijeljen u dva dijela. U prvom dijelu rada opisuje se znanje o mikrostrukturi čelika, dijagramu stanja željezo-ugljik, te različitim fazama kao što su ferit, austenit, perlit i martenzit. Detaljno se obrađuju procesi nitriranja, uključujući svrhu, mehanizam, te različite metode, kao što su nitriranje u plinskoj atmosferi, nitriranje u plazmi, karbonitriranje i nitriranje u solnim kupkama. Također, obrađuju se metode karakterizacije materijala korištene u ovom istraživanju. U drugom dijelu rada fokus je na eksperimentalnom dijelu gdje se provodi nitriranje čelika tipa 20MnCr5 u ekološki prihvatljivoj solnoj kupelji na bazi KNO₃. Ispitivanja uključuju kemijsku analizu, metalografsku analizu, nanoindentaciju i rendgensku difrakciju.
Abstract (english)
This paper addresses the topic of nitriding steel 20MnCr5 using an environmentally friendly salt bath based on KNO₃. This work is divided into two parts. The first part describes the knowledge of the microstructure of steel, the iron-carbon phase diagram, and various phases such as ferrite, austenite, pearlite, and martensite. The nitriding processes are also discussed, including the purpose, mechanism, and different methods such as gas nitriding, plasma nitriding, carbonitriding, and salt bath nitriding. Additionally, the material characterization methods applied in this research are also described. The second part focuses on the experimental part, where nitriding of steel grade 20MnCr5 is conducted in an environmentally friendly salt bath based on KNO₃. The investigations include chemical analysis, metallographic analysis, nanoindentation, and X-ray diffraction analysis.
