Thermogravimetric measurements during decarburization at 840°C and at various ratios of water vapour and hydrogen partial pressure were done. Optical microscopy and SEM were applied to study the oxide layersRaziskali smo vpliv segregiranega in adsorbiranega antimona na razogljičenje in oksidacijo hladno valjane pločevine iz zlitine Fe-Si-Al. Temperatura razogljičenja je bila 840°C, spreminjali pa smo razmerje parcialnega tlaka vodne pare in vodika ?$p(H_2))/p(H_2)$? oksidativne atmosfere. Kinetiko procesov smo s termogravimetrijo, debelino in morfologijo nastalih oksidnih plasti pa smo ugotavljali z optično in vrstično elektronsko mikroskopijoTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of Slovenia
