Abstract
A method for repairing a nitrided surface having a damaged area is disclosed. The method includes introducing the nitrided surface into a bath containing electroless material for a predetermined period of time. The method also includes coating the damaged area with a layer of the electroless material. Further the method subjects the layer to an autofrettage process. The electroless material is heat treated at a predetermined temperature for a predefined time.
