  • Patent number: 9669489
    Abstract: A method of repairing an integrally bladed rotor includes removing a portion of the integrally bladed rotor to create a void in an airfoil, completely filling the void with a single replacement material, and laser shock peening the replacement material. Laser shock peening the replacement material imparts mechanical properties in the replacement material substantially the same as those in the forged material.
    Type: Grant
    Filed: April 30, 2015
    Date of Patent: June 6, 2017
    Assignee: UNITED TECHNOLOGIES CORPORATION

  • Publication number: 20090056096
    Abstract: A method of repairing a turbine engine component, such as an airfoil platform, is provided. The platform includes a surface having a worn or damaged area penetrating the surface, the worn area may result from galling, for example. An electrospark deposition process (ESD) is used to deposit material to the worn or damaged area. The ESD process transfers material from an electrode associated with the ESD machine through a pulsating current that deposits the material onto the worn or damaged area. The material can then be machined to restore the surface to a desired specification. The ESD process is used to repair worn compressor and/or turbine blades and vanes that would otherwise be scrapped.

  • Patent number: 4639388
    Abstract: A reinforced composite structure is disclosed comprising a heat resistant chemically-bonded layer of a ceramic composition mechanically attached to a metallic substrate. The structure includes a metallic anchoring matrix characterized by a plurality of spatially and cooperably arranged reinforcing elements, the matrix being attached to the substrate and projecting from the surface thereof with the spatially arranged reinforcing elements of the matrix collectively defining a ceramic-occupiable zone of finite thickness adjacent to and following the surface configuration of said substrate, the zone having at least confined therein the heat resistant chemically-bonded ceramic in intimate contact with the reinforcing elements. A method for fabricating said composite structure is also disclosed.
