Abstract: A device for electrochemical reduction of a workpiece (10) includes a workpiece (10), an electrode (20), and an electrolyte (30), which is located between electrode (20) and workpiece (10). The electrode (20) is moved close to the workpiece (10) with a small gap dimension (21), and a processing of the workpiece (10) occurs through a flow of current between electrode (20) and workpiece (10) through the electrolyte (30). In addition, a sonotrode is positioned to introduce sound waves.

Abstract: An electrode (10) is provided for electrochemical reduction of a workpiece (20) that is to be treated. The electrode (10) has a predefined contour and contains an electrically conductive material. The electrically conductive material of the predefined contour forms an electrode core (12). The outside of the electrode core (12) is covered with an insulation layer (13). The insulation layer (13) is porous and is made of an electrically non-conductive material.

Abstract: A method for the selective removal of one or more layers from a power unit component, e.g., a turbine blade of a heavy-duty turbine, using high-energy radiation of such a wavelength that the supplied energy is so strongly absorbed by the layer to be removed in each case that the removal threshold of the specific material of the layer to be removed is exceeded, while this removal threshold is not reached in the subsurface to be preserved, a spectrometer connected to a control unit via a light-conducting fiber cable such that the method-specific characteristic values are determinable by spectroscopic methods during the removal of the respective layer and are used for the self-regulating process limitation.

Abstract: A method for producing a component and/or a coating from a vibration-damping alloy or intermetallic compound includes producing the component and/or the coating via thermal spraying.

Abstract: An electrode for the electrochemical fine-boring of workpieces includes an electrode tube for an electrolyte to pass through to reach a workpiece which is to be machined, and an electrical conductor which is connected to the electrolyte, in which electrode the tube, for the purpose of boring bores with the smallest possible diameter, consists of a metal with a substantially amorphous structure, is electrically conductive and is provided on its outer surface, at least in sections, with a nonconductive insulating layer.

Abstract: A structural component made of a base metal composition on a nickel or cobalt basis is provided with a protective coating against oxidation, corrosion, and thermal fatigue. The protective coating and the base metal are made of chemically the same or identical material, whereby the bonding of the protective coating is increased, the tendency to crack is reduced, and the resistance to thermal fatigue is improved. The grain size of the coating is substantially smaller than the grain size of the base metal composition.

Abstract: Surfaces of structural components of metal or the like are protected by depositing a wear-resistant dispersion coating of a matrix metal and hard-material particles embedded in the metal matrix. The depositing is accomplished by a sequential plasma spraying and particle blasting, whereby the hard-material particles are applied separately from the plasma stream to inject the particles into the plastically still deformable matrix metal. The coating steps are performed in an evacuated chamber or in an inert gas environment. These coatings are especially suitable on the blade tips of gas turbine engines, on the sealing fins of labyrinth seals or as "rub" coatings on circumferential rotor surfaces or the like.
