Abstract
The paper describes the experimental determination of spray particle velocities as a function of process parameters, using the particle image velocimetry (PIV) for a better understanding of the properties of sprayed coatings. The PIV image evaluation method is a particle tracking method, that involves a wide range of techniques to determine particle images belonging to the same particle. The PIV system includes two nitrogen lasers with a wavelength of 337 nm, a flat beam illuminator (FBI) which fans out the laser beam over the area of measuring volume, and a CCD camera and control unit for synchronizing the lasers and camera. Particle trajectories in the free jet were determined to gain information on the atmospheric plasma spraying (APS) process. Spray particle velocity profile along the gun axis were measured by varying the key particles and process parameters, including powder feeder rate, combustion chamber pressure and nozzle geometry.
