Abstract
Disclosed is a system and a method for applying both a kinetic spray applied coating layer and a thermal spray applied layer onto a substrate using a single application nozzle. The system includes a higher heat capacity gas heater to permit oscillation between a kinetic spray mode wherein the particles being applied are not thermally softened and a thermal spray mode wherein the particles being applied are thermally softened prior to application. The system increases the versatility of the spray nozzle and addresses several problems inherent in kinetic spray applied coatings.
