  • Coated flange bolt hole and methods of forming the same
    Patent number: 10989223
    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.
    Type: Grant

    Assignee: General Electric Company
    Inventors: Bala Srinivasan Parthasarathy, Guruprasad Sundararajan, Evan Jarrett Dolley, Jr., Leonardo Ajdelsztajn
  • Cleaning compositions and methods for removing oxides from superalloy substrates
    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).
