| Abstract | Abstract Cr12MoV alloy steel was nitrided in a plasma chamber with and without an auxiliary cathode. The results indicate, that at an appropriate distance between the auxiliary cathode and the alloy steel, hollow cathode discharge (HCD) is generated. The HCD is effective and important to harden the alloy steel by promoting the formation of a harder and thicker nitrided layer, which not only contains a nitrogen diffusion zone, where nitridation of the chromium carbide of the alloy occurs as in the case without auxiliary cathode, but also a top compound layer. The distance between the auxiliary cathode and the alloy steel noticeably affected the plasma nitriding kinetics of the Cr12MoV alloy steel. As the distance increases, the thickness of the compound layer and the microhardness of the nitrided layer increase first followed by a decrease. The nitridation mechanisms of the alloy steel with and without auxiliary cathode are discussed. |
