Nozzle Design in Cold Spray Applications

Julio Gutierrez (Materials Technology, HSU) In cold spray, the critical velocity defines the minimum velocity that the particles must reach in order to adhere to the substrate. The more particles exceeding this critical velocity, the higher are the efficiency of the process and the deposit quality. Individually needed process conditions…
