Potential of cold spray as additive manufacturing for Ti6Al4V
Cold spray can be regarded as a high build-speed (300-400 cm3/h) additive manufacturing technology that is capable of non-thermal freeform fabrication on any surface profile. It uses a high pressured and preheated gas stream to accelerate the microparticles via a converging-diverging nozzle to super...
