ABSTRACT:
A method for refurbishing service-degraded gas turbine component can recover the microstructure of the alloy of the gas turbine component, whose material is deteriorated or damaged after its operation, to the extent that is equivalent or more than the characteristic at the time of its manufacture. The method comprises performing a recovery heat treatment, performing a solution heat treatment, and performing an aging heat treatment. The recovery heat treatment heat-treats the component under a predetermined pressure, which is higher than normal pressure, wherein the temperature of the component is increased to a predetermined temperature under the predetermined pressure. The solution heat treatment is processed under reduced pressure or inert gas atmosphere after the recovery heat treatment. The aging heat treatment is processed under reduced pressure or inert gas atmosphere after the recovery heat treatment.
