Abstract: A method for producing a vibration-damping structure combination for damping vibrations for movable masses, having a first structure and a further structure, the further structure movable within a stop surface defined by a first structure surface of the first structure. The method includes a) providing the first structure, having the first structure surface and which defines a coating surface of a coating at least in some sections; b) coating the first structure surface of the first structure with the coating, the coating surface of the coating being applied such that a cavity is formed; c) filling the cavity with the filler; d) curing the filler until the further structure having a further structure surface is formed, which lies against the coating surface; and e) removing the coating, the further structure thus being movable relative to the first structure within the stop surface defined by the first structure surface.

Abstract: The corrosion and erosion resistance of ceramic heat shield elements is improved by the use of yttrium oxide on aluminum oxide as a layer or substrate material is provided. A heat is disclosed having aluminum oxide in the substrate or as a layer on a substrate, wherein yttrium oxide, particularly only yttrium oxide, is present as the outermost layer, particularly directly on the aluminum oxide.

Abstract: The invention relates to a peening device for peening a component with a part to be peened and a part not to be peened. The peening device comprises a chamber with at least one opening located therein, wherein the opening is dimensioned in such a manner that the part not to be peened of the component can be guided there through, and a fixture for retaining the component which features a section which entirely covers the opening of the chamber when the part not to be peened is at least partially guided into said opening, and said section completely encloses the part not to be peened of the component between the adjacent region of the part to be peened of the component and the opening.

Abstract: Conventional welding methods have the disadvantage of producing worse welded joints at the beginning of the process than in the later course of the method. The method in question uses an initializing plate on which the welding process is begun and then once a consistent quality can be achieved for the welded joint continues onto the points for repair.

Abstract: Process for preparing turbine blades or vanes for a subsequent treatment, for example the application of a coating and/or a material-removing operation, wherein the turbine blade or vane has an airfoil, which is delimited at at least one end by an endplate with peripheral surfaces, wherein at least one of the peripheral surfaces is at least partially covered prior to the treatment of the turbine blade or vane. In the process a covering strip is fitted onto at least one peripheral surface to form a plug connection.

Abstract: A holder for holding a metal component part, which has at least one internal passage which is accessible by an opening in an external surface of the component part. The holder is equipped with a bearing element, which comprises a bearing surface, which is designed in such a way that it allows a seating of the component part on the bearing element, and in this case serves as a support for at least a part of the external surface of the component part which has the opening, and a flow passage, which leads through the bearing element, with at least one outlet opening located in the bearing surface. The outlet opening is located in the bearing surface in such a way that, with the component part seated, it lies opposite the opening of the internal passage. Furthermore, the outlet opening in shape and flow cross section is adapted to the opening of the internal passage.

Abstract: A method for coating of a component part is made available, in which an evaporating of a coating material from a material feeder at low ambient pressure is brought about. The component part which is to be coated is located sufficiently near to the material feeder in such a way that, as a result, a depositing of vaporized coating material on the surface of the component part is brought about. A rotation of the component part around a rotational axis takes place while it is located sufficiently near to the material feeder for the bringing about of the depositing of coating material. The rotational axis is pivoted from a standard position towards the material feeder before or during the coating.

Abstract: A method includes coating a product with a metallic coating, in particular a high-temperature component product of a gas turbine, in a vacuum plant. An apparatus coats the product with a metallic coating in a vacuum plant, having a coating chamber and a postheat treatment chamber. Novel process control with regard to a temperature profile, in particular after the application of the metallic coating to the product and before the postheat treatment, involves the ensuring of a minimum temperature at all times, this minimum temperature being relatively higher than room temperature.
