Coating system and method

A method comprising:

• receiving, by a helically shaped first conduit defined by a first chamber disposed in a housing, a first fluid into the housing of an atomizing spray device through a first inlet of the housing, wherein the first conduit is helically shaped about a central axis of an interior chamber;
• receiving, by a helically shaped second conduit defined by a second chamber disposed in the housing, a slurry of ceramic particles and a second fluid into the housing of the atomizing spray device through a second inlet of the housing, the slurry comprising at least a liquid and a solid, wherein the second conduit is helically shaped about the central axis of the interior chamber, with the first chamber of the first conduit extending helically around an exterior of the second chamber of the second conduit;
• mixing the first fluid and the slurry in the interior chamber of the housing of the atomizing spray device to form a mixture in a location between the first and second inlets and one or more outlets;
• and
• directing the mixture outside of the housing of the atomizing spray device as droplets via the one or more outlets such that, based on a discharged amount of the first fluid in the droplets, the first fluid promotes evaporation of the second fluid as the droplets traverse from the housing toward a surface of a component.
