Abstract :
In this study emission spectra for Ti+N2 and Cr+N2 cathodic arc plasmas with N2 pressures between 10-3 and 1 Pa have been detected in the range between 220 and 800 nm. The behaviour of the line intensities of metallic species indicates the importance of ion-molecule collisions. The degree of excitation of the various nitrogen species was characterized by analysis of the population of the vibrational levels. For comparison, similar spectra were taken for Ti and Cr arc discharges with varying argon pressure
