Abstract
A coupon for repairing a part is disclosed. The coupon includes an outwardly threaded body configured to mate with an inwardly threaded opening in a damaged area of the part. The part and/or coupon may include a superalloy. The threaded arrangement converts tensile stresses into shear stresses that allow the repair to exhibit material characteristics as good as or better than the superalloy. A method of using the coupon to repair a part using brazing, and a turbomachine part using the coupon, are also disclosed.
