Chemical carbon removing method of high-pressure turbine blade

The invention provides a chemical carbon removing method of a high-pressure turbine blade, and the operation is carried out by means of exogenic force of ultrasound in combination of reagent. The method in the invention is characterized in that the reagent used in the method is in particular a mixed solution which is constituted by organic reagent, surfactant, inorganic cosolvent and complexing agent. The chemical carbon removing method of the high-pressure turbine blade in the invention has high cleaning efficiency and easy operation; compared with traditional solution used for removing represented by 781, the method in the invention has more obvious effect, and the removing effect is better for special and stubborn carbon deposition; and product percent of pass can be obviously improved when the method is used for producing engine blade. The water-base cleaner required to be protected in the invention and the operation to carry out high-voltage turbine blade chemical carbon removing by utilizing the cleaner
