  • Patent number: 6332272
    Abstract: A method for repairing a turbine blade (10) wherein the tip (16) of the blade is removed (41,43) and a replacement cap is attached by welding (49). The cap may consist of a plate (48) attached by welding and a squealer (54) formed by depositing weld material (52), as illustrated in FIG. 3. The plate and/or squealer may be formed from a material different from the material of the airfoil portion (42) of the blade in order to optimize the performance of the blade.

  • Patent number: 6333484
    Abstract: A process is provided for welding a nickel or cobalt based superalloy article to minimize cracking by preheating the entire weld area to a maximum ductility temperature range, maintaining such temperature during welding and solidification of the weld, raising the temperature for stress relief of the superalloy, then cooling at a rate effective to minimize gamma prime precipitation.
    Type: Grant

    Date of Patent: December 25, 2001
    Assignee: Chromalloy Gas Turbine Corporation
    Inventors: Michael Foster, Kevin Updegrove
  • Patent number: 6165345
    Abstract: A process is provided to strip a metallic coating from a turbine blade comprising attaching the blade to a positive lead from a power supply, submersing a portion of the blade with a metallic coating to be stripped into a bath of acidic electro stripping solution, said bath containing a negative lead from a power supply attached to a conductive grid; and providing a current to the blade in the bath for a period of time effective to remove the coating on the portion of the blade.
