TURBINE EXHAUST CASE WITH COATED COOLING HOLES |
| 摘要 |
An effusion-cooled component includes a base portion defining at least one oversized cooling hole preform. A coating is disposed on the base portion and at least partially covers the oversized cooling hole preform to define a cooling hole. The component may be repaired by removing the coating from a component, visually inspecting the resultant base, and re-coating the base with a coating that oversprays to at least partially fill the oversized cooling preforms to define a plurality of cooling holes. |
