| 20080305276 | Method of Applying Hot Gas Anticorrosion Layers - A method for applying hot gas anticorrosion layers to high-temperature-resistant alloys, either nickel-based or cobalt-based alloys, in the form of a gradient layer consisting of one or more elements of the platinum group in combination with aluminum. The components are introduced into a directional high-temperature, high-enthalpy, free jet of solid, liquid or gaseous precursors in mixing ratios such that defined concentration gradients can be established in the layer. | 12-11-2008 |
| 20090008265 | Method for producing aerodynamic structures during the production of integrally bladed gas turbine rotors - 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. The contours of the or each of the working electrodes are adapted to the contours of the aerodynamic structure, which are produced by means of the respective working electrode, such that a gap between the rotor disk base body and a working electrode are produced in an approximately identical manner during the removal process of the material; d) electrochemically machining the or each aerodynamic structure in an electrochemical sinking by placing the rotor disk base body and the or each working electrode in an electrolyte and by applying voltage and/or current, whereby the applied current and/or voltage is temporally pulsed; e) pressure-rinsing the gap which is filled with electrolytes between the aero-dynamic structure and the or each working electrode by a pulsed movement of the or each working electrode. | 01-08-2009 |
