Abstract

This work analyzes the structure and properties of nitrocarburized diffusion cases generated on M2 type high-speed and 321 stainless steels in a thermochemical. Application of variable process temperatures in the range of 450–600 °C and a variable process duration (2–6 h) enabled observation of growth kinetics of the layers on tested steel grades. Evaluation of properties of the cases obtained comprised hardness measurements and wear tests, carried out by the 3 cylinder-cone method. The evaluation showed that the nitrocarburizing process developed for high-speed and stainless steels yields hard surface layers with beneficial functional properties.
