Abstract

Infrared video thermography was used to evaluate the plasma plume and particle streams created by dc plasma jets operating in air and spraying several types of materials. The temperatures of the plasma plume were measured with the aid of a graphite ‘witness.’ By using the thermography system in an 8khz line scan mode, we were able to obtain data relative to the average velocity of particle groups injected into the plasma. The effects of process parameters could be observed in real time using these methods, showing the potential for real time process control.
