Improved kinetic spray nozzle system design

摘要

An improved kinetic spray nozzle (34') system is disclosed in addition to improved methods for injection particle powders into a nozzle. Utilization of the nozzle (34') enables one to dramatically increase the deposition efficiency of a variety of particles using a kinetic spray process. The improved nozzle (34') includes a powder/gas conditioning chamber (80) that increases the particle residence time within the nozzle (34') thereby enabling one to achieve higher particle temperatures prior to their acceleration in the supersonic portion (54) of the kinetic spray nozzle (34').
