  2. Nitriding - Wikipedia

    en.wikipedia.org/wiki/Nitriding

    For instance, at moderate temperatures (like 420 °C), stainless steels can be nitrided without the formation of chromium nitride precipitates and hence maintaining their corrosion resistance properties. [5] In the plasma nitriding processes, nitrogen gas (N 2) is usually the nitrogen carrying gas. Other gasses like hydrogen or argon are also ...
