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. addit...

In this study, we propose a rapid plasma-assisted nitriding process using H2/N2 mixture gas in an atmospheric pressure plasma jet (APPJ) system to treat the surface of SKD11 cold-working steel order increase its hardness. The generated NH radicals region are used implement ion-bombardment for tempered martensite structure within 18 min form functional nitride layer with increased microhardness ...
