Definitions

  • the invention relates to a nickel-base superalloy having improved oxidation resistance, a powder, a method of welding, and a component.
  • filler metals having a base material-like composition are generally used for tip repair of turbine blades made of ⁇ ⁇ - strengthened nickel-base superalloys.
  • these can be poorly welded due to their high Al and Ti content, so that already modified filler metals have been developed with improved weldability.
  • the oxidation resistance of the filler material in the area of the blade tip is of great interest. In this respect, the new filler metals have so far not optimal properties.
  • Yttrium (Y) 0.008% to 0.012%
  • a filler metal having the following composition is proposed:
  • the alloy can be in the form of a powder and can be electrodeposited onto a component of a substrate.
  • the substrate has build-up welding of the above-mentioned alloy.
