The paper presents the results of the microstructure and selected properties examinations of chromosiliconized and chromized layers produced on a low carbon steel. A steel of DC01 grade was designed for the research. The samples were placed in boxes with a special design, containing a pre-prepared powder mixture. The boxes were closed with lids, sealed hermetically using enamel, preventing oxidation of the load and placed in a furnace heated to processes temperature. The microstructure of the analysed layers were evaluated by light and scanning electron microscope. The thickness, surface of samples were determined. Vickers hardness tests were performed on transverse microsections. The phase composition of chromosiliconized and chromized layers was evaluated using a X-Pert diffractometer. Chemical composition was determined by glow discharge optical emission spectroscopy. Chromosiliconized and chromized samples exhibited an increase in hardness and roughness parameters in comparison to the substrate material. Stresses were measured by the sin2ψ X-ray diffraction method. The results of the study show, that chromosiliconizing and chromizing processes generate the state of the compressive internal stresses on the surface of DC01 steel.
