Effect of Plasma and Gas Nitriding Parameters on Microstructure and Mechanical Properties of DIN 1.2367 Hot Work Tool Steel

This study investigated the hardness and wear on DIN 1.2367 hot work tool steel after applying plasma gas nitriding processes under different conditions. The effect of process temperature N2:H2 mixture ratio was examined in first group specimens, whereas impact nitrogen potential retention time second specimens. In applied to group, increase N2 significantly increased properties material. addition, resistance specimen with highest value increased. Although values had changed, diffusion depth distribution were found be close.
