Abstract
Delamination of thermal barrier coatings ('TBC's') () from superalloy substrates () of components () for turbine engines (), such as engine blades (), vanes (), or castings in transitions (), is inhibited during subsequent cooling passage () formation. Partially completed cooling passages (), which have skewed passage paths that end at a terminus (), which is laterally offset from the passage entrance (), are formed in the superalloy component () prior to application of the TBC layer(s) (). The skewed, laterally offset path of each partially completed cooling passage () establishes an overhanging shield layer () of superalloy material that protects the TBC layer () during completion of the cooling passage ().
