  • Patent number: 9926785
    Abstract: A method for reconditioning a hot gas path part of a gas turbine to flexibly adapt an operation regime of said gas turbine for subsequent operation intervals. The method includes providing a hot gas path part to be reconditioned; removing a predetermined area of the hot gas path part, resulting in a cutout at the hot gas path part; and manufacturing a coupon for insertion into the cutout to replace the removed area of the hot gas path part. The method further includes inserting the coupon into the cutout; and joining the hot gas path part with the coupon. The coupon is manufactured by a selective laser melting method resulting in a fine grain sized material with significantly improved low cycle fatigue lifetime. The hot gas path part is coated, at least in an area including the inserted coupon, with a metallic overlay with improved thermo-mechanical fatigue and oxidation lifetime.

  • Publication number: 20170175534
    Abstract: A blade assembly having a modular structure, wherein the blade elements include at least a rotor blade airfoil, a footboard mounting part and a heat shield. The elements each have at its one ending an interchangeable connection for connection among each other, wherein the connection of the airfoil with respect to the other elements is based on a fixation in radial or quasi-radial extension compared to the rotor axis of the turbomachine. The assembling of the blade airfoil in connection with the footboard mounting part is based on a force-fit or form-fit fixation, or on use of a metallic and/or ceramic surface for the purpose of a friction-locked bonding actuated by adherence interconnecting, or on friction-locking with a detachable, permanent or semi-permanent fixation.

  • Publication number: 20170002661
    Abstract: The disclosure refers to a method of assembling or disassembling a rotor blade or guide vane assembly, wherein the rotor blade or guide vane includes an airfoil and additional structured peripheral members forming at least an inner and/or an outer platform of the rotor blade or guide vane. The airfoil includes at least one airfoil sub-structure designed for anchoring at least one superposed component for the purpose of a thermal protection. The connection between the airfoil sub-structure and the superposed component is supported on friction-locked device, wherein the airfoil sub-structure is formed by a spar and the superposed component includes at least one flow-charged outer shell. Connection between the spar or airfoil understructure and flow-charged outer shell is formed by a force-fit and/or a form-fit fixation or a shrinking joint, wherein the airfoil and additional structured peripheral members is formed by friction-locked device with a detachable, permanent or semi-permanent fixation.

  • Publication number: 20160303674
    Abstract: Method for manufacturing a braze joint gap for connecting a first part to a second part via brazing or soldering, comprising the steps of: adding microstructural elements to a first connecting surface of the first part to be connected to the second part via brazing or soldering; aligning the second part and the first part or an electrode part having a tool contour, which is identical to the contour of the first connecting surface; electro-chemically machining or precise electro-chemically machining a second connecting surface of the second part by polarizing the first part or the electrode part as a cathode and the second part as an anode.

  • Publication number: 20160090848
    Abstract: The invention relates to a method for producing a three-dimensional article or at least a part of such an article made of a gamma prime (??) precipitation hardened nickel base superalloy with a high volume fraction (>25%) of gamma-prima phase which is a difficult to weld superalloy, or made of a cobalt base superalloy, or of a non-castable or difficult to machine metal material by means of selective laser melting (SLM), in which the article is produced by melting of layerwise deposited metal powder with a laser beam characterized in that the SLM processing parameters are selectively adjusted to locally tailor the microstructure and/or porosity of the produced article or a part of the article and therefore to optimize desired properties of the finalized article/part of the article.

  • Publication number: 20160069185
    Abstract: A method for reconditioning a hot gas path part of a gas turbine in order to flexibly adapt an operation regime of said gas turbine for subsequent operation intervals is disclosed. The method includes providing a hot gas path part to be reconditioned; removing a predetermined area of said hot gas path part, resulting in a cutout at said hot gas path part; and manufacturing a coupon for being inserted into said cutout to replace said removed area of said hot gas path part. The method further includes inserting said coupon into said cutout; and joining said hot gas path part with said inserted coupon. The coupon is manufactured by a selective laser melting (SLM) method resulting in a fine grain sized material with significantly improved low cycle fatigue (LCF) lifetime. The hot gas path part is coated, at least in an area comprising said inserted coupon, with a metallic overlay with improved thermo-mechanical fatigue (TMF) and oxidation lifetime.

  • Patent number: 8910361
    Abstract: A method for repairing or reconditioning a damaged component includes working the damaged component by removing a damaged region from the damaged component while creating a cutout corresponding to the damaged region so as to provide a worked component. The worked component is measured and a computer-aided design (CAD) model of a replacement piece based on the measuring and is configured to be inserted into the cutout of the worked component is created. The replacement piece is produced based on the CAD model. The replacement piece and the worked component are connected by joining.

  • Publication number: 20140295087
    Abstract: The invention relates to a method for additively manufacturing an article made of a difficult-to-weld highly-precipitation-strengthened Ni-base super alloy that comprises Al and Ti in the sum of more than 5 wt.-% or a difficult-to weld carbide/solution-strengthened cobalt (Co)-base super alloy, whereby a metal particle mixture of at least a first phase and a second phase is provided as a starting material, said first phase of the mixture being a base material and said second phase of the mixture being a material which is a derivative of the first material and has relative to said material of said first phase an improved weldability, and whereby the metal particle mixture is processed by means of an additive manufacturing process which is one of selective laser melting (SLM), selective laser sintering (SLS), electron beam melting (EBM), laser metal forming (LMF), laser engineered net shape (LENS), or direct metal deposition (DMD).
