Research of boride layers growth kinetics on C45 carbon steel
This study reports an evaluation of borides formed on C45 steel. Pack boronizing has been carried out in temperature range 870 – 970 °C with durations 4 – 8 h. Average thickness of boride layers ranges from 60, 6 to 181, 2 µm. Through application of basic laws of diffusion, values of frequency factor and activation energy have been determined and practical empirical expression for boronizing of C45 has been derived. Also analyzed is the change of volume share of boride phase concerning cross section of the layer. Based on volume share of boride phase as well as measured microhardnesses of base material and boride phase, change of cross sectional layer hardnesses is determined and analyzed.
