Research of boride layers growth kinetics on C15 carbon steel

This study reports on formation of borides on C15 carbon steel. Pack boronising has been carried out in temperature range 870–970°C with durations 4–8 h. Average thickness of boride layers ranges from 69.9 μm to 239.2 μm. The aim of this study is to investigate influence of boronising temperature and duration onto average thickness of boride layer, thickness of the compact part of layer and its toothness as well as the change of volume share of boride phase concerning cross section of the layer. Analysis showed the existence of influence of mentioned factors on observed properties of boride layer. As a result, mathematical models showing their functional correlation have been obtained through application of statistical methods.
