摘要： A method for the formation of at least one passage hole in a high-temperature substrate is described. For each desired passage hole or group of passage holes, a node is first formed on the exterior surface of the substrate, by a laser consolidation process. The node functions as a pre-selected entry region for each passage hole. The passage hole can then be formed through the node, into the substrate. Related articles, such as turbine engine components, are also described.

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.

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.
