    摘要： A method of fabricating a component is provided. The method includes depositing a fugitive coating on a surface of a substrate, where the substrate has at least one hollow interior space. The method further includes machining the substrate through the fugitive coating to form one or more grooves in the surface of the substrate. Each of the one or more grooves has a base and extends at least partially along the surface of the substrate. The method further includes forming one or more access holes through the base of a respective one of the one or more grooves to connect the respective groove in fluid communication with the respective hollow interior space. The method further includes filling the one or more grooves with a filler, removing the fugitive coating, disposing a coating over at least a portion of the surface of the substrate, and removing the filler from the one or more grooves, such that the one or more grooves and the coating together define a number of channels for cooling the component.

The electrode is made of an electrically conductive material and has insulated areas in which the electrically conductive material is coated with an insulating material, and exposed areas of metal or conductive material. The insulated areas and exposed areas extending in rows substantially along a longitudinal axis of the electrode. The electrode is first positioned in a substantially circular hole.

    摘要： A turbine portion, for example a turbine blade, for exposure in a hot fluid flow includes at least one internal cooling passage disposed therein. A cooling fluid is introduced within the cooling passage(s) to maintain the bulk temperature of the turbine portion at some acceptable temperature level. A plurality of concavities are disposed on the interior surface of the cooling passage. In one embodiment, the concavities are formed on the interior surface of cooling passage in an array pattern such that a spiral bulk fluid motion is obtained, similar to that which would be formed by a helical rib, but without the rib. The concavity surface pattern serves to enhance heat transfer to the same degree as the conventional rib rougheners, but with significantly less pressure loss due to friction. The spiral motion of the bulk cooling fluid also serves to recirculate central coolant to the heat transfer surface, thereby making the heat exchange process more effective than that for turbulated surfaces.

    摘要： A method of fabricating a component is provided. The method includes forming one or more grooves in a surface of a substrate, where the substrate has at least one hollow interior space. Each of the one or more grooves extends at least partially along the substrate surface and has a base and a top. The base is wider than the top, such that each of the one or more grooves comprises a re-entrant shaped groove. The method further includes forming one or more access holes through the base of a respective groove, to connect the groove in fluid communication with respective ones of the hollow interior space(s), and disposing a coating over at least a portion of the substrate surface. The one or more grooves and coating define one or more re-entrant shaped channels for cooling the component. A component with one or more re-entrant shaped channels and a method of coating a component are also provided.

    摘要： A method of fabricating a component is provided. The method includes depositing a structural coating on an outer surface of a substrate, where the substrate has at least one hollow interior space. The method further includes forming one or more grooves in the structural coating. Each groove has a base and extends at least partially along the substrate. The method further includes depositing at least one additional coating over the structural coating and over the groove(s), such that the groove(s) and the additional coating together define one or more channels for cooling the component. The method further includes forming one or more access holes through the base of a respective groove, to connect the respective groove in fluid communication with the respective hollow interior space, and forming at least one exit hole through the additional coating for each channel, to receive and discharge coolant from the respective channel. A component with cooling channels formed in a structural coating is also provided.
