ITSC 2017, Thermal Spray 2017: Proceedings from the International Thermal Spray Conference, 719-724, June 7–9, 2017,
... Abstract Cold spray is continuously expanding for the repair of parts made of aluminum-based alloys. Beyond repair applications, the process is now expected to be exploited efficiently for the additive manufacturing of shaped parts. However, up to now, cold spray is limited to the achievement...

ITSC 2021, Thermal Spray 2021: Proceedings from the International Thermal Spray Conference, 229-234, May 24–28, 2021,
... Abstract In this paper, the phenomenological behaviour of gas flow and particles motion during cold spraying has been studied. Observations of particles behaviour show two features: a uniform jet over a short distance ahead of the nozzle exit and then, a progressive dispersion. These behaviours...

ITSC2000, Thermal Spray 2000: Proceedings from the International Thermal Spray Conference, 419-422, May 8–11, 2000,
... Abstract In cold spraying, coatings are formed by a high velocity impact of solid particles. The particles are accelerated in a supersonic gas jet at temperatures of only a few hundred degrees centigrade. In contrast to thermal spray processes no melting of the particles and negligible heating...
