Effect of nitrogen on surface morphology of layers

Popis výsledku v původním jazyce

This article deals with chemical composition and mechanical properties of plasma nitrided layers after chemical-heat treatment process. Experiments are focused on creation of clusters of nitrogen on the surface of evaluated material. Peculiarity of this experiment is created sophisticated technological process suitable for creation of nitride layers inside cavities with really small diameters. The conditions of process are designed to provide strictly defined nitride layers about defined parameters. In this case the nitrided layers were applied to bars of 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 was applied for increasing of surface hardness of material in deep cavities. In the evaluation of surface structure the new typical marks on the surface of material after plasma nitriding process were found. Mechanical properties of evaluated material were significantly increased.
