Simulation of the Influence of Spray Parameters on Particle Properties in APS

This paper investigates the influence of process parameters on plasma sprayed particles. Through simulations, the authors show that particle velocity is largely a function of trajectory, which is influenced by plasma composition, powder properties, injection velocity, particle size distribution, and kinetic energy. Depending on kinetic energy, the particles are deflected by the high viscous region around the flow core, they enter the core, or they pass through it into the slow outer flow on the opposite side. Paper includes a German-language abstract.
