Abstract

An atomizing spray device includes a housing having plural inlets and one or more outlets fluidly coupled with each other by an interior chamber. The inlets include a first inlet shaped to receive a first fluid and a second inlet shaped to receive a slurry of ceramic particles and a second fluid. The interior chamber in the housing is shaped to mix the first fluid received via the first inlet with the slurry received via the second inlet inside the housing to form a mixture in a location between the inlets and the one or more outlets. The interior chamber in the housing also is shaped to direct the mixture formed inside the housing as droplets outside of the housing 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.

First claim

What is claimed is:

1 . An atomizing spray device comprising:
a housing having plural inlets and one or more outlets fluidly coupled with each other by an interior chamber, the inlets including a first inlet shaped to receive a first fluid and a second inlet shaped to receive a slurry of ceramic particles and a second fluid, wherein the interior chamber in the housing is shaped to mix the first fluid received via the first inlet with the slurry received via the second inlet inside the housing to form a mixture in a location between the inlets and the one or more outlets, the interior chamber in the housing also shaped to direct the mixture formed inside the housing as droplets outside of the housing 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.

2 . The atomizing spray device of claim 1 , wherein the first fluid includes air.

3 . The atomizing spray device of claim 1 , wherein the inlets are located in a first surface of the housing and the one or more outlets are located in a second surface of the housing that intersects the first surface.

4 . The atomizing spray device of claim 1 , wherein the housing includes at least two of the outlets located in the housing to direct the mixture in opposite directions out of the housing.

5 . The atomizing spray device of claim 1 , wherein the one or more outlets are located in the housing to direct the mixture in at least one direction that is perpendicular to a direction in which the first fluid or the second fluid is received into the inlets.

6 . The atomizing spray device of claim 1 , wherein the one or more outlets are located in the housing to direct the mixture in at least one direction that is oriented at an acute angle relative to a direction in which the first fluid or the second fluid is received into the inlets.

7 . The atomizing spray device of claim 1 , wherein the chamber in the housing is shaped to mix the first fluid and the slurry in a location that is midway between the inlets and the one or more outlets in the housing.

8 . The atomizing spray device of claim 1 , wherein the chamber in the housing is shaped to mix the first fluid and the slurry in a location that is closer to the one or more outlets than the inlets.

9 . The atomizing spray device of claim 1 , wherein the chamber in the housing forms a first conduit portion that carries the first fluid in the housing and a second conduit portion that carries the slurry in the housing, wherein the first conduit portion helically winds around the exterior of the second conduit portion.

10 . The atomizing spray device of claim 1 , wherein the first and second inlets define separate openings into the chamber in the housing, with the first inlet encircling the second inlet at one end of the housing.

11 . The atomizing spray device of claim 1 , wherein the one or more outlets of the housing are shaped to spray the mixture onto the surface of the component at a standoff distance of at least two centimeters.

12 . A method comprising:
receiving a first fluid into a housing of an atomizing spray device through a first inlet of the housing; receiving a slurry of ceramic particles and a second fluid into the housing of the atomizing spray device through a second inlet of the housing; mixing the first fluid and the slurry in an 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.

13 . The method of claim 12 , wherein the first fluid includes air.

14 . The method of claim 12 , wherein the second fluid includes an alcohol.

15 . The method of claim 12 , wherein directing the mixture outside of the housing includes directing the mixture in opposite directions out of the housing.

16 . The method of claim 12 , wherein mixing the first fluid and the slurry occurs in a location that is midway between the inlets and the one or more outlets in the housing.

17 . An atomizing spray device comprising:
a housing having plural inlets through a first surface of the housing and one or more outlets through a different, second surface of the housing, the housing including an interior chamber that fluidly couples the inlets with the one or more outlets, the inlets including a first inlet shaped to receive a first fluid and a second inlet shaped to receive a slurry of ceramic particles and a second fluid, wherein the interior chamber in the housing is shaped to mix the first fluid received via the first inlet with the slurry received via the second inlet inside the housing to form a mixture in a location between the inlets and the one or more outlets, the interior chamber in the housing also shaped to direct the mixture formed inside the housing as droplets outside of the housing 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.

18 . The atomizing spray device of claim 17 , wherein the first fluid includes an alcohol.

19 . The atomizing spray device of claim 17 , wherein the inlets are located in the first surface of the housing and the one or more outlets are located in the second surface of the housing that intersects the first surface.

20 . The atomizing spray device of claim 17 , wherein the housing includes at least two of the outlets located in the housing to direct the mixture in opposite directions out of the housing.

21 . The atomizing spray device of claim 17 , wherein the chamber in the housing forms a first conduit portion that carries the first fluid in the housing and a second conduit portion that carries the slurry in the housing, wherein the first conduit portion helically winds around the exterior of the second conduit portion.
