Method for removing a layer

摘要

The removal of corrosion products (10) such as metallic- or ceramic layer from a component (1) such as gas- or steam turbine or a rotor- or guide blade or a combustion chamber lining, comprises applying a foil material on the corrosion products to damage the products before a fluorine ion cleaning or an acid treatment. When applying the foil material, a larger contact surface through a molten salt is produced, so that a removal rate in the cleaning or the acid treatment of the products is greater than without the damaging of the corrosion products.

When applying the foil material, a larger contact surface through a molten salt is produced, so that a removal rate in the cleaning or the acid treatment of the products is greater than without the damaging of the corrosion products. Rifts (7) that damage the products are generated in the products. Delaminations are produced between the products and an upper surface, on which the products are arranged. The material that is present on the products is heated by microwaves and a laser and the component is further reprocessed. The corrosion products are present on a metallic substrate (4).
