Chromatic monitoring of plasma jets used for plasma spraying

A chromatic detection system was designed and tested for monitoring the optical emission from a d.c. arc plasma jet with and without powder particles heated in the plasma. The chromaticity parameters measured are correlated with the arc current, gas flow rate and substrate position.
