We claim:

1. A ring, comprising:

a body;

a gas flow system disposed within the body, comprising;

an arc shaped groove;

a circumferential groove, wherein the circumferential groove has a smaller radius than a radius of the arc shaped groove;

one or more inner channels that fluidly couple the circumferential groove to the arc shaped groove; and

a plurality of nozzle regions, wherein the plurality of nozzle regions are disposed at an inner surface of the body, and are each fluidly coupled to the circumferential groove by a respective nozzle channel.

2. The ring of claim 1 , wherein the gas flow path further comprises an outer channel, and a plugging element is disposed in the outer channel.

3. The ring of claim 1 , wherein a circumferential groove coating is disposed over at least a portion of the circumferential groove, and an arc shaped groove coating is disposed over at least a portion of the arc shaped groove.

4. The ring of claim 3, wherein the circumferential groove coating and the arc shaped groove coating both comprise nickel.

5. The ring of claim 3, wherein the body comprises aluminum (Al), the circumferential groove coating comprises anodized aluminum, and the arc shaped groove coating comprises anodized aluminum.

6. The ring of claim 1 , further comprising:

a circumferential groove seal element, wherein the circumferential groove seal element is disposed over the circumferential groove to form a first enclosed region; and

an arc shaped groove seal element, wherein the arc shaped groove seal element is disposed over the arc shaped groove to form a second enclosed region,

wherein the one or more inner channels are configured to fluidly couple the first enclosed region to the second enclosed region.

7. The ring of claim 6, wherein the circumferential groove seal element comprises circumferential seal tabs, and the arc shaped seal element comprises arc shaped seal tabs.

8. The ring of claim 6, wherein the circumferential groove seal element is welded to the body, and the arc shaped groove seal element is welded to the body.

9. A method for manufacturing a ring, comprising:

forming a gas flow system in a body of the ring, the gas flow system comprising:

an arc shaped groove;

a circumferential groove, wherein the circumferential groove has a smaller radius than the radius of the arc shaped groove;

one or more inner channels that fluidly couple the circumferential groove to the arc shaped groove; and

a plurality of nozzle regions, wherein the plurality of nozzle regions are disposed at an inner surface of the body, and are each fluidly coupled to the circumferential groove by a respective nozzle channel; and

depositing a circumferential groove coating and an arc shaped groove coating, wherein the circumferential groove coating is disposed over at least a portion of the circumferential groove, and the arc shaped groove coating is disposed over at least a portion of the arc shaped groove.

10. The method of claim 9, wherein the gas flow path further comprises an outer channel, the method further comprising sealing the outer channel with a plugging element.

11. The method of claim 9, wherein the circumferential groove coating and the arc shaped groove coating each comprises nickel (Ni), and the arc shaped groove coating comprises nickel (Ni).

12. The method of claim 9, further comprising:

positioning a circumferential groove seal element over the circumferential groove to form a first enclosed region; and positioning an arc shaped groove seal element over the arc shaped groove to form a second enclosed region,

wherein the one or more inner channels are configured to fluidly couple the first enclosed region to the second enclosed region, and the nozzle channels are each fluidly coupled to the first enclosed region.

13. The method of claim 12, wherein the positioning the circumferential groove seal element further comprises welding the circumferential groove seal element to the body, and the positioning the arc shaped groove seal element further comprises welding the arc shaped groove seal element to the body.

14. A method of cleaning a component, comprising:

rinsing the component with a first rinsing chemical for a first rinsing time, the component having:

one or more inlet holes in the component;

one or more outlet holes in the component; and a gas flow system within the component, wherein the gas flow system fluidly couples the one or more inlet holes and the one or more outlet holes;

the first rinsing chemical delivered with a first rinsing pressure, the first rinsing chemical delivered into the one or more inlet holes, through the gas flow system, and through the one or more outlet holes;

purging the component with a first purge gas for a first purge time, the first purge gas delivered with a first purge pressure, the first purge gas delivered into the one or more inlet holes, through the gas flow system, and through the one or more outlet holes; and

rinsing the component with a second rinsing chemical while heating the component to a rinsing temperature for a second rinse time, wherein the second rinsing chemical comprises deionized water, and wherein the rinsing the component comprises exposing the component to ultrasonic vibrations.

15. The method of claim 14, wherein the first rinsing chemical comprises deionized water.
