Abstract
A method of repairing a superalloy component () wherein a section () of the component containing a plurality of service-induced cracks () is removed, then a replacement section () of superalloy material is installed with a structural braze joint () containing no boron or silicon. The replacement section may have a textured surface (() to enhance bonding with an overlying thermal barrier coating (). The replacement section may be pre-formed to standardized dimensions in expectation of a typical service-induced crack pattern, and the removed section excavated accordingly. The interface between the replacement section and the component may be shaped to provide a mechanical interlock there between.
