摘要： An object is to reduce changes in mechanical properties of a gas turbine blade base material during repair or regeneration of a gas turbine blade. For this purpose, a gas turbine blade after being operated is washed by being immersed into a strong alkaline washing solution, and the gas turbine blade after being washed with the strong alkaline washing solution is washed with water. The gas turbine blade after being washed with water is then washed by being immersed into a weak acid washing solution, and the gas turbine blade after being washed with the weak acid washing solution is subjected to heat treatment. The gas turbine blade after the heat treatment is then immersed into a strong acid washing solution, whereby the coating formed on the surface of the gas turbine blade is removed.
