Sažetak
Kinetics of boride layers formation on C15 carbon steel has been investigated in this paper. Pack boronizing is carried out at a temperature range of 870 – 970 °C in durations of 4 – 8 h. Average thickness of obtained layers ranges from 65, 3 to 215, 5 µm. Values of frequency factor (3, 02 x 10-4 m2/s) and activation energy (195, 43 kJ/mol) are determined by means of Arrhenius equation. Based on these values, empirical expression showing functional relationship between boride layer thickness and boronizing temperature and duration has been obtained.
