Applying the principles of physical chemistry, a mathematical model of the process has been set up and a computer program for calculating technological parameters has been developed. Based on the results of the experimental work and literature data, the assumption that the speed of the process is proportional to the thermodynamic activity of carbon in the austenite has been provenV delu je opisan difuzijski proces rasti karbidne plasti na površini jekla. Upoštevajoč principe fizikalne kemije smo naredili matematični model procesa in računalniški program za izračun tehnoloških parametrov procesa. Na podlagi rezultatov eksperimentalnega dela in literaturnih virov smo potrdili, da je hitrost procesa premo sorazmerna aktivnosti ogljika v avstenituTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaInštitut za kovinske materiale in tehnologije
