Abstract

This paper deals with explanation of plasma nitriding fundamentals of and specific technical features of this technology. Preparation of samples and performing of plasma nitriding process is described in the experimental part. Plasma nitriding process was carried out on the DIN 16MnCr5 steel at 500 °C under pressure of 280 Pa in the nitriding atmosphere mixture of H2 and N2 (l / h) for 10, 20 and 30 h. The nitrided steel samples were studied using the GDOES spectrometry, optical microscopy, and hardness and microhardness testing. Measurements of nitride layers properties of selected steel were evaluated using the experimental methods in accordance with standards. The influence of diffusivity and of plasma nitriding conditions on the nitride layers depth was comprehensively assessed. Relation between plasma nitriding duration and depth of nitride layer was found and explained. The measurements have shown that the plasma nitriding duration has a significant influence on the nitride layer depth.

Keywords: Plasma nitriding, microhardness, nitrided layer, nitriding duration
