Abstract

The article deals with chemical composition and mechanical properties of plasma nitrided layers after plasma nitriding process. Experiments are focused on using of plasma nitriding process for surface treatment of cavities with diameter of 8 mm. Nitrided layers were applied to steel 32CrMoV12-10 which were subsequently evaluated by metallographic, GDOES, XRD microanalysis and microhardness methods. The results of measurement showed trends of chemical composition of alloying elements after chemical-heat treated process through the length of cavity. Plasma nitriding process is applied for increasing of surface hardness of material in deep cavities. Mechanical properties of tested material were significantly increased. Experimental work showed characteristics connection among alloying elements. Properties and thickness of nitrided layer are dependent on nitride formed elements contained in core of material. The diffusion coefficient should be addict on nitride formed elements as well.
