Abstract: Nozzle block vanes having damaged trailing edge sections are repaired by removing the damaged section and replacing it by a new forged replacement trailing end section. The replacement section is coated with an erosion resistant coating leaving an uncoated border on three sides, preferably beveled. The coated section is welded to the vane and walls of the nozzle block and the weld portion ground to give a uniform contour between the vane and replacement section. The block is heat treated or the heat affected zone heat treated to provide a repaired vane.
