Abstract: A decoating device for axially symmetric components, particularly from aircraft engines is provided, the decoating process being carried out through the use of a decoating fluid-which is brought on a localized basis into contact with the component to be decoated, a receptacle for holding the decoating fluid being provided that rotates at least about one axis of rotation, and the decoating fluid surface forming a rotation paraboloid in response to the rotation, the component(s) to be decoated on a localized basis being accommodated in the receptacle and being dipped on the radially outer side into the decoating fluid. A decoating device is thereby devised which makes it possible for radially symmetric components to be decoated in the radially outer region in a simple process.

Abstract: A method for stripping a component, in particular a gas turbine component, to completely or partially remove a multilayer or sandwich antiwear coating from the surface of the component, the antiwear coating including at least one relatively hard ceramic layer and at least one relatively soft metallic layer is disclosed. According to the present invention, in order to remove the multilayer or sandwich antiwear coating, the component is placed in a bath of an alkaline electrolyte, the component placed in the electrolyte being stripped at a current density of between 1 A/dm2 and 20 A/dm2.

Abstract: A method for selectively removing a first layer from an engine component including the first layer, a base material and a second layer forming a bond connecting the first layer to the base material is provided. The method includes applying a salt melt to at least one section of the engine component including at least one portion of the second layer so the bond formed by the second layer between the base material and the first layer is at least weakened.

Abstract: The invention relates to a method for coating or decoating a component, in particular a gas turbine component, wherein, in order to regionally or partially coat or decoat a component, the component is preferably completely covered with a covering medium, and wherein the covering medium is removed from only those surface regions of the component in which the coating or decoating of the component is supposed to take place, so that a surface region of the component which is not to be coated or decoated is covered by the covering medium. According to the invention, the covering medium is removed by means of water jet machining.

Abstract: A method for electrochemically stripping components, especially gas turbine components, is provided. According to the method, the component from which a coating is to be removed is connected to a positive terminal of a voltage source or current source while an electrode is connected to a negative terminal thereof. An electrode is used that is precisely adapted to a region of the component to be stripped such that a gap between the region of the component to be stripped and the electrode is approximately constant over the entire region to be stripped.
