Turbine components with cooling features and methods of manufacturing the same

摘要

The present disclosure is directed to the use and manufacture of cooling features within a component used in a hot gas path, such as within a turbine. In one embodiment, channels are formed within an external surface of the component and filled with a removable material. The external surface and channels may then be coated with one or more layers, such as a structural layer and/or top coat. The removable material may then be removed to leave the channels free of the removable material.

主权项

1. A method for manufacturing a turbine component, comprising:
forming one or more channels in an external surface of the turbine component; forming one or more holes between the one or more channels and an interior region of the turbine component; mechanically pressing a single filler material into the one or more channels so as to deform the single filler material to conform to and substantially fill the one or more channels, wherein the single filler material comprises a metal or a metal alloy wire that conforms to a cross-sectional shape of the respective channels; applying one or more coatings to the external surface of the turbine component over the one or more channels filled with the metal or metal alloy wire; forming one or more holes through the coatings; and removing the metal or metal alloy wire from the channels.
