Abstract
An article of manufacture includes an article body portion (36); at least one pedestal (58A, 60A, 84, 86) integrally formed with the article body portion (36), and disposed at an outer periphery of (52), and structurally coupled to the article body portion (36); and at least one internal feature (72) disposed at least partially within the article body portion (36) and at least partially within the pedestal (58A, 60A, 84, 86). At least a portion of the internal feature (72) is hollow.
Claims17
An article of manufacture comprising:
- an article body portion;
- at least one pedestal integrally formed by additive manufacturing with the article body portion, the at least one pedestal disposed at an outer periphery of the article body portion, and structurally coupled to the article body portion;
- at least one internal feature, the at least one internal feature disposed at least partially within the article body portion and at least partially within the at least one pedestal;
- and
- a coating disposed on the article body portion and the at least one pedestal;
- wherein at least a portion of the at least one internal feature is hollow, and
- wherein the at least one pedestal forms a barrier between the at least one internal feature and the coating preventing access to the at least one internal feature, thereby preventing the coating from being disposed within the at least one hollow portion of the at least on internal feature.
An article comprising:
- an airfoil body, the airfoil body extending from a leading edge to a trailing edge, the airfoil body extending from a pressure side to a suction side, the airfoil body extending from a root portion to a tip portion;
- at least one internal cavity disposed within the airfoil body;
- at least one pedestal integrally formed by additive manufacturing with the airfoil body, the at least one pedestal protruding from an outer periphery of the airfoil body, the at least one pedestal structurally coupled to the airfoil body;
- and
- at least one film cooling hole, the at least one film cooling hole disposed at least partially within the airfoil body and at least partially within the at least one pedestal, wherein the at least one pedestal is configured to prevent access to the at least one internal cavity,
- wherein the at least one film cooling hole is in fluid communication with the at least one internal cavity.
A method of forming a component comprising:
- selecting an orientation for the component being formed such that one or more structure aligns with at least one feature of the component;
- forming the component and the one or more structure by additive manufacturing with the one or more structure disposed on the at least one feature;
- coating the component and the one or more structure;
- and
- blending at least one surface of the component with at least one surface of the one or more structure;
- wherein the at least one feature is disposed at least partially in the component and at least partially in the one of more structure, wherein the at least one structure is configured to prevent access to the at least one feature of the component.
