  • Publication number: 20200370443
    Abstract: System for selectively contacting a cleaning composition with a surface of a turbine engine component is presented. The system includes a cleaning apparatus and a manifold assembly. The cleaning apparatus includes an upper portion and a lower portion defining a cleaning chamber configured to allow selective contact between the cleaning composition and a surface of the first portion of the turbine engine component. The upper portion includes a plurality of fill holes in fluid communication with the cleaning chamber, and the lower portion includes a plurality of drain holes in fluid communication with the cleaning chamber. The manifold assembly is configured to selectively circulate the cleaning composition from a reservoir to the cleaning chamber via the plurality of fill holes, and recirculate the cleaning composition from the cleaning chamber to the reservoir via the plurality of drain holes. Methods for selectively cleaning a turbine engine component is also presented.

  • Patent number: 10639719
    Abstract: In one embodiment, a method of manufacturing a metal part using a laser or electron beam during a powder bed additive manufacturing process includes melting each of a number of layers of metal powder of the metal part with an effective amount of energy using the laser or electron beam to form the metal part such that at least one or more portions of the metal part have a critical amount of residual strain. The method also includes performing a heat treatment on the metal part that transforms the residual strain into substantially distributed coincidence site lattice (CSL) grain boundaries, low angle grain boundaries, or both in the metal part.

  • Patent number: 10569309
    Abstract: A cleaning system and method uses a tank holding a fluid detergent and an equipment assembly formed from a plurality of discrete components joined together. One or more ultrasound transducers remove one or more deposits on the equipment assembly by generating and propagating high frequency ultrasound waves into the fluid detergent while the equipment assembly is in contact with the fluid detergent.

  • Patent number: 10377968
    Abstract: Methods for cleaning a superalloy substrate having engine deposits on its surface are provided. The method may include applying a permanganate solution onto the surface of the superalloy substrate, and applying a ferric chloride based cleaning composition onto the surface of the superalloy substrate. The ferric chloride based cleaning composition includes ferric chloride and at least one of nitric acid and phosphoric acid, such as within a solvent system (e.g., an aqueous solution including water).

  • Publication number: 20180223870
    Abstract: Methods for repairing flange bolt holes and the resulting flange bolt holes are provided. The methods and products include the incorporation of a coating system comprising a corrosion resistant layer, which can be formed by resistance plug welding, slurry or sol-gel processing, or thermal/cold spray processing. The corrosion resistant layer can be a super alloy or ceramic material and is different than the base material of the flange bolt hole. Corrosion of the flange bolt hole can be reduced or prevented from occurring with the use of the coating system.

  • Publication number: 20180094217
    Abstract: A cleaning composition, and method for use of the cleaning composition to clean metal surfaces, such as the surfaces of turbomachinery components, is presented. For example, a method includes contacting a surface of an article with a cleaning composition, wherein the article comprises a metal and wherein the surface includes an oxide; and removing the cleaning composition from the surface. The cleaning composition has a viscosity of at least 104 poise, and comprises a thickening agent and an acidic matrix having selective reactivity with the oxide.
