Abstract
A gas turbine engine component includes a passage and a geometrically segmented coating section adjacent the passage. The geometrically segmented coating section includes a wall that has a first side bordering the passage and a second side opposite the first side. The second side includes an array of cells, and there is a coating disposed over the array of cells. The coating defines an exterior side. A cooling passage extends through the wall and the coating. The cooling passage fluidly connects the passage and the exterior side.
Claims24
A gas turbine engine component comprising:
- a passage;
- and
- a geometrically segmented coating section adjacent the passage, the geometrically segmented coating section including
- a wall having a first side bordering the passage and a second side opposite the first side, the second side including an array of closed-sided cells defined by cell sidewalls,
- a coating disposed in the array of closed-sided cells, the coating defining an exterior side, and
- a cooling passage that extends through the wall and the coating, the cooling passage fluidly connecting the passage and the exterior side.
A gas turbine engine comprising:
- a compressor section;
- a combustor in fluid communication with the compressor section;
- and
- a turbine section in fluid communication with the combustor,
- at least one of the turbine section or the compressor section including a gas turbine engine component having
- a passage, and
- a geometrically segmented coating section adjacent the passage, the geometrically segmented coating section including
- a wall having a first side bordering the passage and a second side opposite the first side, the second side including an array of polygonal cells defined by cell sidewalls,
- a coating disposed in the array of polygonal cells, the coating defining an exterior side, and
- a cooling passage that extends through the wall and the coating, the cooling passage fluidly connecting the passage and the exterior side.
A method for fabricating a geometrically segmented coating section, the method comprising:
- depositing a coating on a wall, wherein the wall includes a first side and a second side opposite the first side, the second side includes an array of closed-sided cells defined by cell sidewalls, and a cooling passage that extends from the first side and through the array of cells to an encapsulation, and the coating is deposited in the array of cells;
- removing a portion of the coating along the array of cells;
- and
- removing the encapsulation to open the cooling passage.
