    摘要: A process for creating a near-surface cooling passage in an air-cooled turbomachine component. The process entails forming a channel in a surface of a surface region of the component so that the channel is open at the surface and fluidically connected to a first cooling passages within the component. A metallic layer is then deposited on the surface and over the channel without filling the channel. The metallic layer closes the channel at the surface of the surface region to define therewith a second cooling passage within the component that is fluidically connected to the first cooling passages. A coating system is then deposited on the metallic layer to define an outermost surface of the component. The second cooling passage is closer to the outermost surface of the component than the first cooling passages.

    摘要: A turbine blade closure system composed of a closure member capable of being friction welded in an aperture in a hollow-cast turbine blade to prevent the escape of cooling fluids from an internal cavity in the turbine blade. In one embodiment, the aperture is formed in the turbine blade during the manufacturing process as a result of one or more support projections used to position a core block in a turbine blade mold.
