    초록 The blade of the gas turbine must withstand the most severe combination of temperature, stress and enviroment. After certain period operation, various types of damages are easily found and the damages are identified as due to the turbine operating mode. In order to have with initially similar mechanical properties, the blade of nickel-based superalloy components is passed by a replacement repair process. The fluoride ion cleaning (FIC) process is used to assist in the successful welding repair of nickel-based superalloy components. This work is to study the FIC influence for a gas turbine blade that was serviced 25,748 EOH after first overhaul. The conditions of blade samples were observed by optical microscope and SEM, and the chemical composition of flaws in the blade was investigated by EDS. The condition of the blade was examined from the gamma prime phase morphology and size, because the gamma prime phase coarsening rate depends largely on the exposure time and temperature.
