2. Nitriding
In a similar way to carburation (see article ), nitriding involves the incorporation of nitrogen by diffusion into the metal, followed by nitride precipitation (figure 9 ). This can result in hardening or embrittlement of the material, particularly at welds. The precipitation of chromium nitrides can lead to dechroming of the material, affecting its resistance to corrosion.
2.1 Pure nitrogen atmospheres
The effect of nitriding in atmospheres containing 100% nitrogen is still poorly understood. Nitrogen is considered inert in the molecular state. At high temperatures (of the order of 1,000°C), nitrogen dissociates and forms nitrides with chromium,...
