摘要： Delamination of thermal barrier coatings (“TBC's”) (276) from superalloy substrates (262) of components (260) for turbine engines (80), such as engine blades (92), vanes (104, 106), or castings in transitions (85), is inhibited during subsequent cooling passage (270) formation. Partially completed cooling passages (264), which have skewed passage paths that end at a terminus (268), which is laterally offset from the passage entrance (266), are formed in the superalloy component (260) prior to application of the TBC layer(s) (276). The skewed, laterally offset path of each partially completed cooling passage (264) establishes an overhanging shield layer (269) of superalloy material that protects the TBC layer (276) during completion of the cooling passage (270).

摘要： A gamma prime nickel-based superalloy is provided, which can include a combination of Ti and Zr in a total weight amount sufficient to form cellular precipitates located at grain boundaries of the alloy, wherein the cellular precipitates define gamma prime arms that distort the grain boundaries at which they are located. The Hf-containing, gamma prime nickel-based superalloy and/or the gamma prime nickel-based superalloy can include cellular precipitates that are predominantly located at grain boundaries of the alloy such that the cellular precipitates define gamma prime arms that distort the grain boundaries at which they are located. The superalloys can further include finer gamma prime precipitates (e.g., cuboidal or spherical precipitates) than the cellular precipitates.
