Patent number: 7967183Abstract: The invention relates to a method for repairing components comprising a base material with an oriented microstructure, wherein the repair point comprises a correspondingly oriented microstructure as the surrounding base material. According to the inventive method, solder is applied in the region of a point which is to be repaired and is soldered to the component by means of a heating effect produced by a device. A temperature gradient, i.e., approximately a temperature characteristic, is produced during the heating effect, said temperature characteristic ranging from a high to a low temperature in the region of the point which is to be repaired.Type: GrantFiled: January 28, 2005Date of Patent: June 28, 2011Assignees: Siemens Aktiengesellschaft, MTU Aero Engines GmbHInventors: Dirk Goldschmidt, Matthias Oechsner, Michael Ott, Uwe Paul, Ursula Pickert, Eckart Schumann, Beate Seiler, Robert Singer, Jan Steinbach, Andreas Volek, Volker Vosberg

Patent number: 7584669Abstract: Method for recording microstructural changes in a layer system component. A specific material parameter of the component is measured. The layer system may include an alloy substrate and an alloy or porous ceramic layer. The material parameter may be measured a plurality of times. The measured material parameter may include electrical capacitance, specific heat capacity, peltier coefficient or magnetic susceptibility. The material parameter may first be measured on a new component and subsequent measurements may be performed at a time interval after operational use. The recorded material parameter is then used to determine microstructural changes in the substrate or the layer material of the component caused by changes in precipitation, cracks, or depletion of an alloying element.Type: GrantFiled: February 14, 2005Date of Patent: September 8, 2009Assignee: Siemens AktiengesellschaftInventors: Michael Dankert, Martin Feldhege, Stefan Irmisch, Matthias Oechsner, Eckart Schumann, Werner Stamm

Publication number: 20070194773Abstract: To detect contaminants on turbine components of a turbine, at least one current oscillation characteristic value of at least one turbine component is determined. Said value is preferably compared to an oscillation reference value. This permits contaminants to be detected, as the weight of the latter modifies the oscillation characteristic value of the turbine component.Type: ApplicationFiled: March 1, 2005Publication date: August 23, 2007Inventors: Michael Dankert, Matthias Oechsner

Patent number: 6939603Abstract: A component (10) having a thermal barrier coating (14) exhibiting an improved resistance to thermal shock. A plurality of stress relieving cracks (22) are formed at the free surface (24) of the thermal barrier coating as a result of the expansion of an inclusion (20) having a higher coefficient of thermal expansion than that of the surrounding matrix material (16). The inclusions function as crack initiators during the fabrication process as well as crack arrestors preventing the propagation of the cracks farther into the matrix material. The inclusion material may be selected to have an evaporation temperature that is less than the peak matrix material processing temperature, wherein the inclusion material will evaporate to leave a plurality of voids (30). In one embodiment, a superalloy substrate (12) is coated with a ceramic thermal barrier coating material having a plurality of spherical polymer inclusions disposed below its free surface.Type: GrantFiled: March 1, 2002Date of Patent: September 6, 2005Assignee: Siemens Westinghouse Power CorporationInventor: Matthias Oechsner
