Abstract
A method for remanufacturing turbine vane clusters of gas turbine engines is disclosed. Concepts and techniques for salvaging undamaged vanes from a damaged vane cluster are developed. In accordance with the method taught, protective coatings on the vane clusters are removed and residual stresses in the vanes are relieved before salvageable vanes are separated from their original vane cluster.
