Monitoring plasma jets containing micro particles with chromatic techniques

Abstract

A description about the use of the chromatic methodology for monitoring an arc plasma jet utilised for heating micro particles for forming plasma sprayed coatings is given. It is shown that the behaviour of both the plasma and heated micro particles are distinguishable from their different coordinates on an H‐S polar map. Calibration with a standard ribbon lamp would appear feasible for tracking the temperature of the plasma heated micro particles.
