Abstract: A turbine blade tip cooling system includes a turbine blade having a tip cavity, a tip rail surrounding at least a portion of the tip cavity and at least one internal cooling cavity. The tip rail has an inner rail surface, an outer rail surface, an end surface and at least one tip rail pocket open at the end surface and fluidly connected to the at least one internal cooling cavity that carries a coolant. A tip rail cooling insert attaches to the at least one tip rail pocket, and has insert cooling channel(s) and a coolant collection plenum for directing coolant from the at least one internal cooling cavity to the insert cooling channel(s).

Abstract: Methods of reducing an initial cross-sectional area of a hole in a component to a predetermined cross-sectional area including preparing a composition comprising at least an aluminum alloy with a melting temperature higher than aluminum, applying the composition to an interior surface of the hole, and then heating the component to cause a metal within the component to diffuse from the component into the composition and react with the aluminum alloy in the composition to form a coating on the interior surface of the hole. The heating step is performed to selectively modify the initial cross-sectional area of the hole and thereby directly attain the predetermined cross-sectional area thereof.

Abstract: A tip rail cooling insert for attaching into a tip rail pocket in a tip rail of a turbine blade is disclosed. The insert includes a first inner layer defining at least one first insert cooling channel therein, the first inner layer including a pair of spaced legs defining a first coolant collection plenum with at least the tip rail pocket for directing coolant from at least one internal cooling cavity in the turbine blade to the at least one first insert cooling channel. Each of the pair of spaced legs has an angled outer end configured to accommodate rounded inner corners of the tip rail pocket. A first outer layer is on a first side of the first inner layer, and a second outer layer is on a second side of the first inner layer.

Abstract: A hybrid diffusion-brazing process and hybrid diffusion-brazed article are disclosed. The hybrid diffusion-brazing process includes providing a component having a temperature-tolerant region and a temperature-sensitive region, brazing a braze material to the temperature-tolerant region during a localized brazing cycle, then heating the component in a furnace during a diffusion cycle. The brazing and the heating diffusion-braze the braze material to the component, and the localized brazing cycle is performed independent of the diffusion cycle in the hybrid diffusion-brazing process. The hybrid diffusion-brazed article includes a component, and a braze material diffusion-brazed to the component with a filler material. The filler material has a melting temperature that is above a tolerance temperature of the component.
