The plasma spraying process is used to coat surfaces which are subjected to extreme conditions, e.g. rocket nozzles in the aerospace industry. The basic outline of the pro- cess is to inject metal or ceramic particles into a plasma jet generated by an electric arc. The particles are melted by the high temperature and accelerated towards the component to be coated (the substrate) by the high fluid velocities inside the plasma jet. When impacting on the substrate the particles solidify in a few milliseconds to form a strongly bonded coating. At Fraunhofer Chalmers Centre a software for simulating electrostatic rotary bell spray painting is being developed and used in the automotive industry. In this the- sis it has been investigated how well this software, IPS Virtual Paint, can predict a plasma spraying process. Two test cases were defined and simulated. Data from previous detailed simulations of the plasma jet and its close surroundings was used to define the virtual plasma gun. Physical tes
