The samples were annealed in a gas mixture of H$_2$ and N$_2$ with different oxigen potential is at 970$^{\circ}$C for 5 minutes. The oxide layer was studied by using different electron spectroscopy techniques. We found that the oxide layer was a mixture of porous ?$\Fe_3O{4}$? and compact ?$\FeAl_2O{4}$? (hercynite). A synthetic hercynite standard was prepared for XPS and HRAES measurementsŠtudirali smo sestavo oksidne plasti na površini visoko legirane neorientirane elektro pločevine med razogljičenjem. Vzorce smo žarili v plinski mešanici vodika in vodne pare pri temperaturi 970$^{\circ}$C, 5 minut, pri različnih vsebnostih vodne pare. Oksidno plast smo analizirali z metodami elektronske spektroskopije in ugotovili, da je porozna oksidna plast ?$\Fe_3O{4}$?, kompaktna pa ?$\FeAl_2O{4}$? oziroma hercinit. Izdelali smo sintetični hercinit, ki nam je rabil kot standard za HRAES- in XPS-raziskaveTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaInštitut za kovinske materiale in tehnologije
