Abstract:
The restoring process machines out a crack in the platform of a turbine blade to form a pocket that then receives a plug of compatible material. The plug is brazed in place and the blade is the machined and cleaned to present a clean fresh surface where the plug is inserted. The plug has a lower coefficient of thermal expansion so that the plug area has less compressive stresses in the repaired area.
