Abstract

An atomizing spray device includes a housing having inlets that receive a first fluid and a slurry of ceramic particles and a second fluid. The inlets are fluidly coupled with outlets by an interior chamber that mixes the first fluid with the slurry to form a primary mixture of the first fluid and first atomized droplets of the slurry. A first outlet on a first side of the housing and a second outlet on the first side of the housing are shaped to change the primary mixture to form a secondary mixture of the first fluid and second atomized droplets of the slurry. The first outlet sprays the secondary mixture onto a first surface as a first layer of coating and the second outlet sprays the secondary mixture onto the first surface as a second layer of coating while the housing moves in a direction along the first surface.
