Abstract
Plasma spray systems are used to deposit high temperature materials on substrates to form coatings. Thermal analysis of these systems will assist in determining spray parameters for different materials. Infrared videothermography was used to measure temperature profiles and particle velocities of these plasma spray systems. Thermal gradients were defined, and an equatorial temperature profile was estimated. Changes in particle velocities were determined, and the thermal effect of particles on the plasma during spraying was observed. The thermography system was able to investigate high temperature plasmas above 15,000°C, study particle movements, and analyze flame profiles.
