Patent number: 11958150Abstract: A method for repairing a damaged leading or trailing edge region of a metallic turbine blade, which has a suction-side blade wall, a pressure-side blade wall and a leading edge and a trailing edge, includes: removing the damaged leading or trailing edge region, with a cutout being formed; providing a replacement part which can be inserted in form-fitting fashion into the cutout and which restores the intended geometry of the turbine blade; inserting the replacement part in form-fitting fashion into the cutout in a predetermined insertion direction, and cohesively connecting the replacement part to the turbine blade, wherein mechanical connection of the replacement part and turbine blade using separate fastening elements is performed in addition to the cohesive connection.Type: GrantFiled: August 6, 2021Date of Patent: April 16, 2024Assignee: Siemens Energy Global GmbH & Co. KGInventors: Björn Anders, Reiner Anton, Constantin Garske, Kay Krabiell, Heiko Lammers, Ricardo Nilsson, Daniel Vöhringer, Jörg Ziege

Patent number: 11724343Abstract: A method for repairing an at least externally coated hollow component. The direct mechanical machining of a coated component after use removes the need for a coating-removal and selective hollowing step and a selective repair of cracks, since a design adaptation leads to a component being engineered or used such that it can be used again as a result of external dimensional stipulations.Type: GrantFiled: October 12, 2020Date of Patent: August 15, 2023Assignee: Siemens Energy Global GmbH & Co. KGInventors: Heiko Lammers, Daniel Vöhringer

Patent number: 11703481Abstract: A method for checking a component to be produced in an additive manner, having the steps of mechanically exciting at least one additively constructed layer of the component during the additive production of the component, measuring a mechanical response signal of the component, and displaying a warning and/or interrupting the additive production of the component if the mechanical response signal lies outside of a specified tolerance range. A device for the additive production of a component, includes a device for mechanically exciting the at least one additively constructed layer of the component, a measuring unit for measuring the mechanical response signal of the component, and a control unit. The control unit is designed to display the warning and/or interrupt the additive production if the mechanical response signal lies outside of a specified tolerance range.Type: GrantFiled: December 5, 2016Date of Patent: July 18, 2023Assignee: SIEMENS ENERGY GLOBAL GMBH & CO.Inventors: Christoph Haberland, Matthias Jungbluth, Andreas Kreutzer, Heiko Lammers, Thomas Lorenz, Martin Regener, Kathrin Sperlich, Danny Tomuschat

Patent number: 11260453Abstract: A method for additive production of a component, which includes the additive construction of the component on a component platform having an opening, wherein, during the first part of the additive construction of the component an auxiliary structure is produced additively around the opening of the component platform. The method further includes the introduction of a device through the opening into a cavity defined by the auxiliary structure, wherein, during a second part of the additive construction, following the first part of the additive construction, properties of the component to be produced are influenced and/or measured by the device. A component is produced by the method and an apparatus for the additive production of the component, includes the component platform having the opening and the closure.Type: GrantFiled: November 25, 2016Date of Patent: March 1, 2022Assignee: Siemens Energy Global GmbH & Co KGInventors: Christoph Haberland, Andreas Kreutzer, Heiko Lammers, Thomas Lorenz, Martin Regener, Kathrin Sperlich, Danny Tomuschat

Patent number: 9850778Abstract: Yttria stabilized zirconia (YSZ) particles (40) form a thermal barrier layer (58) on a metal substrate (24). The YSZ particles have a porous interior (52, 54) and a fully melted and solidified outer shell (50). The thermal barrier layer may have porosity greater than 12%, including porosity within the particles and inter-particle gap porosity. Inter-particle gaps may be greater than 5 microns. The thermal barrier layer may exhibit elastic hysteresis and an average modulus of elasticity of 15-25 GPa. A bond coat (44A, 44B) may be applied between the substrate and the thermal barrier layer. The bond coat may have a first dense MCrAlY layer (44A) on the substrate and a second rough, porous MCrAlY layer (44B) on the first MCrAlY layer, the bond layers diffusion bonded to each other and to the substrate.Type: GrantFiled: November 18, 2013Date of Patent: December 26, 2017Assignee: Siemens Energy, Inc.Inventors: Walter L. Riggs, Gunnar W. Swanson, Heiko Lammers
