The process is conducted in shaft and bell furnances, with a temperature scale between 500°C and 600°C in an ammonia atmosphere. Because of the chemical decay of ammonia at the component, the nitrogen diffuses into the surface and forms a diffusion and compound layer. It is important to  note that it is not possible to nitrate passivated metallic surfaces and highest value should be placed on cleaning the components prior to treatment. Only low and medium alloyed steels can be nitrated.

The duration of the process and temperature have direct impact on the outcome. Additional enrichment of the surface with carbon is called  nitrocarburization. A  post oxidation is possible as well and can be conducted within the cooling or seperately. A modern process control system guarantees by control and documentation the highest possible reproducibility.
