Nickel-based superalloy mixed powder having zirconia for directed energy deposition, nickel-based superalloy directed energy deposition structure and method of manufacturing the same

Abstract

Provided is a nickel-based superalloy mixed powder having zirconia for directed energy deposition, a zirconia contained nickel-based superalloy directed energy deposition structure having uniform microstructure and excellent hardness and a method for manufacturing the same. The method of manufacturing the zirconia contained nickel-based superalloy directed energy deposition structure includes, providing a nickel-based superalloy powder having a first average particle size; providing a zirconia powder having a second average particle size smaller than the first average particle size; forming a mixed powder by mixing the nickel-based superalloy powder and the zirconia powder; and forming nickel-based superalloy directed energy deposition structure by performing directed energy deposition with the mixed powder using a laser.
