Abstract
The present paper is a review of recent works related to the optical emission spectroscopy applied to the determination of ground state densities of N atoms in Ar-N2 flowing post-discharges. The effect of small quantities of H2 in the Ar-N2 discharge on N atom densities within the post-discharge has been analysed. The authors demonstrate that optical emission of Na impurity may be applied to the determination of the vibrational temperature of N2(X,v) states at the temperatures usual for nitriding of metals in Ar-N2 post-discharge. From the diagnostic of Ar-N2 post-discharges, it is clearly specified that nitriding of iron base alloys in a flowing post-discharge reactor is originating in N atoms, especially when a few H2 molecules are admixed into the Ar-N2 discharge. Finally, correlation between the N-atom density and the thickness of the iron nitrided layers when H2 is introduced into the Ar-N2 discharge are given.
