Abstract
A method of repairing a seal wire groove is disclosed, the groove forming an annular structure having an outer surface and an inner surface and defining an original profile when new, comprising the steps of: removing a less-than-annular portion of the original profile of the groove to remove damaged portions of at least one of the inner and outer surfaces thereby forming a void; adding new material to the void; and shaping the new material to form a new profile of the groove.

A method of repairing a seal wire groove, said groove forming an annular structure having an outer surface and an inner surface and defining an original profile when new, said method comprising the steps of:
- removing a less-than-annular portion of said original profile of said groove to remove damaged portions of at least one of said inner and outer surfaces thereby forming a void;
- adding new material to said void;
- and
- shaping said new material to form a new profile of said for containing a seal wire.
A method of repairing a seal wire groove in a gas turbine engine compressor disk, said groove forming an annular structure having an outer surface and an inner surface and defining an original profile when new configured to accommodate a seal wire of generally rectangular cross section, said method comprising the steps of:
- removing a less-than-annular portion of said original profile of said groove via mechanical machining to remove damaged portions of at least one of said inner and outer surfaces thereby forming a void defining a localized repair area;
- adding new material to said void via a Hyper-Velocity Oxy-Fuel (HVOF) process;
- and
- shaping said new material via mechanical machining to form a new profile of said for containing a seal wire.
- wherein said new profile is substantially similar to said original profile.
