Abstract
A superalloy component such as a gas turbine engine blade () having a ceramic thermal barrier coating () is repaired using a textured repair foil (). A degraded region of the thermal barrier coating is removed () and the underlying superalloy material surface is prepared () for re-coating. The repair foil is includes a layer of boron-free braze material () and a layer of superalloy material () having a textured surface (). The foil is brazed () to the prepared surface during a solution heat treatment effective to homogenize the braze (). A new area of thermal barrier coating () is applied over the foil with a bond that is enhanced by the texturing of the foil surface.
