ABSTRACT:
A method of maintaining a non-obstructed interior opening in a kinetic spray nozzle is disclosed. The method includes the steps of providing a mixture of particles including first particle population and a second particle population; entraining the mixture of particles into a flow of a gas at a temperature below the melt temperature of the particle populations; and directing the mixture of particles entrained in the flow of gas through a supersonic nozzle to accelerate the first particle population to a velocity sufficient to result in adherence of the first particle population on a substrate positioned opposite the nozzle. The operating conditions of the kinetic spray system are selected such that the second particle population is not accelerated to a velocity sufficient to result in adherence when it impacts the substrate. The inclusion of the second particle population maintains the supersonic nozzle in a non-obstructed condition and also enables one to raise the main gas operating temperature to a much higher level, thereby increasing the deposition efficiency of the first particle population.
