Nitrocarburizing is a process in which nitrogen and carbon are diffusing in the material. The temperature used for this process is between 500-680°C. In this situation nitrogen is the element that diffuses more than carbon. The obtained layer could be from 0.2-0.6 mm. The properties of the layer are high hardness, very good wear and corrosion resistance. The controlled atmosphere is based on nitrogen + ammonia + CO2 (endogas, exogas, methane) mixtures.
The process is used for alloyed, stainless, tool steels and can be done in the following furnaces:
