Research on morphology of boride layers obtained on C45 steel

This study focuses on morphology of borides formed on C45 steel. Pack boronizing is carried out at a temperature range of 870 – 970 °C in durations of 4 to 8 h. Through use of linear method, average thicknesses of boride layers as well as volume share of boride phase concerning cross section of the layer are determined. Taking the morphology into account, there are two main parts of boride layer: compact part and toothed part. In this study, boride layer is divided in compact part and toothed part based on volume share, and in continuation, the influence of boronizing temperature and duration on boride morphology is analysed. Analysis showed existence of influence of mentioned factors not only on boride layer thickness, but also on its morphology.
