Plasma nitriding provides many advantages compared to other technologies. Focusing on environmental aspects, two points are particularly worthwhile. Plasma nitriding is carried out at comparatively low temperatures (450-580°C) and process times are much shorter. Hence, it is way more energy efficient than other processes.
Moreover, plasma treated components have a longer life span, put out less scrap and require less re-working. Thereby, savings are achieved along the entire life cycle of the component. Additionally, the process gases - nitrogen, hydrogen and argon - are non-toxic. Toxic gases like ammonia are not required at all.
