AbstractA downstream radial powder injection cold spray system has been developed and validated using aluminum-based (Al, Al-l2Si and Al-7075) powders. Numerical simulation is performed to simulate the gas flow and particle movement behavior in the spray nozzle. Particle velocities at the nozzle exit were measured using an optical dianostic method. The numerical simulation agrees well with the particle velocity measurement results. Microstructures and microhardness of the aluminum coatings deposited on Al-6061 aluminum substrates were investigated and were compared with results from the literature using upstream axial powder injection cold spray systems.
