Summary:According to the actual structure and size of plasma spraying gun, a simulation model based on the Euler-Euler multi-phase model was established with the parameters of medium energy in this study. The distribution nephogram of the temperature and velocity fields of tungsten powder particles and the working gas used in the spraying process were obtained. Additionally, through the mass distribution nephogram, the heating and melting processes of tungsten powder particles in the flame flow were analyzed, and the deposition behavior of the molten droplets of the tungsten powder was investigated. In order to verify the correctness of the simulation, an experiment is performed with the parameters of low energy, medium energy and high energy. This study was of significance in the development of spraying technology, as well as for the improvement on product performance.
