摘要 |
<p>A method of repairing a superalloy component (22) wherein a section (24) of the component containing a plurality of service-induced cracks (18, 20) is removed, then a replacement section (26) of superalloy material is installed with a structural braze joint (28) containing no boron or silicon. The replacement section may have a textured surface ((38) to enhance bonding with an overlying thermal barrier coating (42).

The interface between the replacement section and the component may be shaped to provide a mechanical interlock there between.</p> |
