Abstract
An atomizing spray nozzle device includes plural inlets that receive different phases of materials of a coating. The device also includes an atomizing zone housing portion fluidly coupled with the inlets and shaped to mix the different phases of the materials into a mixed phase slurry. The device also includes a plenum housing portion fluidly coupled with the atomizing housing portion along the center axis of the device. The plenum housing portion includes an interior plenum that is elongated along the center axis of the device. The plenum is configured to receive the mixed phase slurry from the atomizing zone. The device also includes one or more delivery nozzles fluidly coupled with the plenum. The one or more delivery nozzles provide one or more outlets from which the mixed phase slurry is delivered onto one or more surfaces of a target object as a coating on the target object.
