Abstract: Disclosed is a system and a method for simultaneously applying a kinetic spray coating and a thermal spray coating onto a substrate using a single application nozzle to produce a combined coating. The system may include a higher heat capacity gas heater to permit both the thermal spray and the kinetic spray. The method involves providing two populations of particles to the nozzle simultaneously wherein one population is thermally softened in the nozzle under the spray parameters and the other is not. The system increases the versatility of the spray nozzle and addresses several problems inherent in kinetic spray applied coatings.

Abstract: A gas collimator (40') for use in a kinetic powder spray system is disclosed. The collimator (40') reduces turbulence of the main gas and results in significant increases in the amount of particles deposited on a substrate using the system. The collimator (40') enables the main gas temperature to be reduced. Also disclosed is a low pressure injection method for a kinetic spray system. The coaxial, low pressure injection method enables the use of low pressure powder feeders, which are low cost, technologically mature, and widely available commercially.
