Patent number: 9612218Abstract: This method for determining whether an acidic aqueous solution is usable or not comprises: a first detection step (S21) in which the solution concentration of an acidic aqueous solution resulting from pickling is determined; a second detection step (S23a, S23b) in which the concentration of a specific metal in the acidic aqueous solution resulting from pickling is determined, the metal having been contained in the coating layer; a concentrated-solution addition step (S25b) in which in cases when the solution concentration is equal to or less than a predetermined first threshold, a concentrated acidic aqueous solution is newly added; and a determination step (S24a, S24b) in which in cases when the concentration of the specific metal is equal to or higher than a predetermined second threshold, it is determined that the acidic aqueous solution is unusable.Type: GrantFiled: February 7, 2014Date of Patent: April 4, 2017Assignee: MITSUBISHI HEAVY INDUSTRIES, LTD.Inventors: Tetsuji Kawakami, Hiroyuki Mitsui, Yoshiyuki Inoue

Patent number: 8876978Abstract: 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.Type: GrantFiled: February 14, 2008Date of Patent: November 4, 2014Assignee: Mitsubishi Heavy Industries, Ltd.Inventors: Tetsuji Kawakami, Ikumasa Koshiro, Rumi Haruna, Yoshitaka Uemura
