In gas nitriding, nitrogen is provided in the form of ammonia gas. The process takes place in bell and pit type furnaces at temperatures of 500°C to 600°C. Due to the chemical decomposition of the ammonia on the component, the nitrogen diffuses into the surface and forms a diffusion and bonding coating.
Process duration and temperature have a direct influence on the result. Hardness, nitration or hardening depth and coating thicknesses can be influenced by targeted process control. The additional enrichment of the surface with carbon is referred to as nitrocarburizing. A subsequent oxidation can be carried out during the cooling process or separately.
Low to medium alloyed steels are nitridable, but no passivated metallic surfaces. Component cleaning before treatment is of the greatest importance.
