  • Patent number: 9347327
    Abstract: A system and method for repairing a turbine. The method includes applying a coating on an outer surface of a tenon that extends from a stator vane. The tenon may be inserted at least partially into an opening defined by an inner shroud segment of the turbine. A bushing may be inserted at least partially into the opening in the inner shroud segment of the turbine such that the tenon becomes at least partially disposed within an opening defined by the bushing. A bolt may be inserted through the opening in the bushing and at least partially into an opening defined by the tenon. The bolt may be threadably engaged with the tenon.
