Plasma Nitriding & Nitrocarburising

  • PDF

Nitriding and nitrocarburizing in pulse glowing discharge (pulsed plasma nitriding and nitrocarburising) are efficient methods to increase hardness and wear-resistance, corrosion resistance and durability in large cycle exploiting of metals and alloys.

Basic technological advantage of nitriding technique is the low temperature at which the process is directed (450 – 600°C) resulting in partly volume deformations and piece distortions, and there is no phase change of the structure of the processed tools. Thus for all tools and parts nitrided by this method, but being made by appropriate steels, there is no need of additional treatment after the process of nitriding.

Compared to gas and liquid nitriding where the working environment (gas or liquid) is insufficiently active or toxic; ion-nitriding is processed by "illumination transmission of electricity into plasma", and the process is completely environmental. Heating of parts is done directly from plasma without additional heaters.
