  • Patent number: 7479208
    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).

  • Publication number: 20090008265
    Abstract: The invention relates to a method for the production of aero-dynamic structures during the production of integrally bladed gas turbine rotors. Aerodynamic structures of an integrally bladed gas turbine rotor are produced on a rotor disk base body, whereon the end contours are precise, by removing material according to an electrochemical removal process, i.e. by means of an electrochemical machining (ECM)-process. The method comprises the following steps: a) preparing a rotor disk base body which is made of a material which is difficult to machine; b) removing the material which is between the blade wings until a specific dimension is obtained, according to a removal process; c) preparing at least one working electrode in order to finish at least one aerodynamic structure of an integrally bladed gas turbine rotor.

  • Publication number: 20070144916
    Abstract: A method is disclosed for manufacturing blades arranged on the outside circumference of an impeller in a BLISK technology by contouring by means of an electrochemical machining method using molded cathodes. The surface of the blades in contouring is equipped with a negative structure in relation to the molded cathode surface and at the same time a structure that minimizes boundary layers in one manufacturing step. The electrochemical machining method is a pulsed method.

  • Publication number: 20060085979
    Abstract: A method for manufacturing integrally bladed rotors (preferably gas turbine rotors) is provided. The method includes the steps of a) providing a basic rotor body; b) placing the basic rotor body into an electrolyte; c) electrochemically machining the basic rotor body by simultaneously manufacturing a plurality of unmachined blades; and d) subsequently machining the unmachined blades to provide hydrodynamic surfaces, in particular a suction side and a pressure side, in the area of each unmachined blade.

  • Publication number: 20060081481
    Abstract: An electrode and method for the electrochemical machining of a workpiece is disclosed. The electrode is designed as a cathodically polarized tool electrode. It has a geometry that corresponds to the geometry to be removed from the workpiece, at least in a machining range, and perviousnesses in the electrode to allow an electrolyte to flow through and exit at the electrode surface, at least in the area of the machining range. The perviousnesses are formed by a porous design of the electrode and/or by artificially created openings in the electrode or the electrode surface. The porosity distribution and/or the number, arrangement and configuration of the openings is selected such that a uniform electrolyte flow and/or electrolyte exchange at the electrode surface is ensured at least in the machining range of the electrode.

  • Publication number: 20060081480
    Abstract: A method for machining workpieces provides a machining electrode, which is guided at a specific distance to the workpiece. An electrolyte is provided between the workpiece and the machining electrode, through which an operating current flows between the machining electrode and the workpiece. The operating current results from an operating voltage (UA), which is produced at the machining electrode, the workpiece being connected to ground. To perform the machining procedure, the distance between the machining electrode and the workpiece is regulated and the operating voltage (UA) is determined in such a way that the resulting operating current is a DC current or a pulsed DC current—i.e., the operating voltage is a DC voltage of fixed or specific dimension. A measuring voltage (UM) is superimposed on the operating voltage (UA) for producing the operating current.

  • Publication number: 20060049055
    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.

  • Patent number: 6910729
    Abstract: A vehicle window includes a pane of self-darkening or laminated glass and a function layer made of a low-emission material disposed on an inside surface of the pane. The function layer reflects a first infrared radiation into the vehicle and reduces an emission of a second infrared radiation from the glass pane into an interior of the vehicle. In addition, a method for regulating a thermal comfort of a passenger in an interior of a vehicle includes the steps of providing a self-darkening glazing as protection against glare and heat, disposing an IR-reflecting transparent layer on the glazing in form of a coating or film, reflecting an infrared radiation emitted from the vehicle interior back into the vehicle interior using the IR-reflecting transparent layer, and reducing a heat radiated by the glazing into the vehicle interior.
