چکیده انگلیسی
In this work, various soft chemical stripping methods are studied based on pitting acids and agents as well as oxidising acids in organic and aqueous media. The effect of the immersion time is also investigated. The feasibility of the dissolution reactions has been evaluated through thermodynamic calculations. It will be shown that the most effective baths are those containing relatively high concentrations of pitting reagents in organic media. Aqueous solutions lead to pitting of the superalloy. The stripping mechanisms have been discussed in terms of the dissolution of coating grain boundaries once the solution has passed through the oxide scales.
