Component, method of manufacturing the component, and method of cleaning the component

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;
• a circumferential groove seal element disposed over the circumferential groove to form a first enclosed region;
• a circumferential groove metal portion, wherein the circumferential groove metal portion is disposed between the body and the circumferential groove seal element;
• circumferential seal tabs disposed at a bottom of the circumferential groove seal element, wherein the circumferential seal tabs separate the circumferential groove metal portion from the circumferential 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, a portion of the circumferential groove seal element, a portion of the circumferential seal tabs, and the arc shaped groove coating is disposed over at least a portion of the arc shaped groove.
