Abstract
A method is directed toward decoating a parent body, provided with an anti-corrosion coating, of a turbine blade. An outer part of the anti-corrosion coating is removed abrasively by a water jet. An inner part of the anti-corrosion coating is then removed chemically. This combination permits efficient and cost-effective decoating of the turbine blade.
