1. An atomizing spray nozzle device comprising:
a housing having a first inlet and a second inlet that receive different phases of materials used to form a coating from coaxial tubes, the first inlet disposed inside the second inlet, the housing having an interior annular chamber that surrounds an interior body and that is shaped to mix different phases of materials into a two-phase mixture of ceramic-liquid droplets in a carrier gas within the interior annular chamber,
the housing including two or more delivery nozzles from which the two-phase mixture of the ceramic-liquid droplets are directed in the carrier gas onto surfaces of a turbine engine as a coating, wherein the two or more delivery nozzles include at least one delivery nozzle that is oriented in a radial direction away from a center axis of the housing and at least two delivery nozzles being at different angles with respect to one another to form a fan-like arrangement that provides for a larger coverage area, the center axis extending from the first inlet and the second inlet to a delivery end, and
at least a portion of the housing having a tapered shape that increases in size along the center axis.
