Abstract
The article deals with mechanical properties of nitrided layers which were created by plasma nitriding technology. Technology of plasma nitriding is generally used to increase the surface hardness, fatigue strength, wear and corrosion resistance of steels. Experiments were focused on using plasma nitriding process for surface treatment of cavities with diameter of 6 and 8 mm. Nitrided layers were applied to steel 42CrMo4 which were subsequently evaluated by metallography, GDOES, microanalysis and microhardness method. The results of experiments have shown that plasma nitriding process is applicable to mentioned cavities. The surface hardness of material was significantly increased. The measurements have shown that the surface hardness and microhardness are dependent on the content of nitrogen in material.

Key words
nitriding, microhardness, nitrided layer, Nht thickness
