Process for controlling a glow discharge plasma nitriding process and system using the same

The control of a plasma assisted nitriding process includes optical emission spectroscopy measurement of the emissions from two reactive and emissive species in the discharge plasma to provide two analogue signals (D1i, D2i); treating these signals to obtain a parameter (Xi) and comparing this with...
