Paper Abstract

Even at the present time it is not always possible to obtain satisfactory results from plasma spraying in aerospace applications. This is because there is insufficient theoretical and experimental understanding of all the parameters which influence the deposition process. Among the important factors which must be further explored are the velocities and the flow characteristics of the plasma jet. In this paper we present new results from measurements utilizing a Laser Dual Focus Velocimeter. Velocity and turbulence intensity measurements of both the plasma and powder particles were taken at tank pressures of 50 and 1013 mbars.
