Abstract

Plasma temperatures and spray particle velocities were measured in a low pressure plasma spray system. Plasma temperatures of 6,540–9,050 K were calculated from argon atomic emission spectra by the Boltzmann slope method. Peak particle velocities up to 365 m/s were measured with a laser velocimeter for 44 pm Al2O3, spray powder. Measured particle velocity distributions show a strong dependence on process chamber pressure over the range of 50–600 Torr.
