In this study, particle image velocimetry (PIV) is used to measure WC particle velocity during HVAF spraying. Measured velocities are compared with calculated velocities obtained using open source CFD software. Numerical simulation is also used to investigate particle temperatures. With the HVAF gun used, maximum particle velocity is reached around 18 mm from the nozzle exit with a corresponding gas temperature of 1400 K.
