摘要：

During the filming by a high-speed video camera, the images of a particle flux moving in a plasma jet during the spraying of powder coatings on machine parts are recorded. The distributions of key physical parameters of particles in the flux cross sections of the plasma jet with the help of algorithms of the filtering and selection of the particle tracks from the images are computed. The distribution of the particle velocities along the jet axis was computed. The processing of the image stream with a small frame exposition time allowed determining the particle bulk density distribution along the plasma jet axis. As a result of images processing for cross section at the end of the flux the dependence of differential density distribution of particles vs. orientation angle of their tracks directions relative to the flux axis has been obtained.
