Method for producing component made of nickel based superalloy containing hafnium

摘要

The present invention relates to a method for manufacturing a part made of a nickel-based single crystal superalloy containing hafnium. This method involves producing a nickel-based single crystal superalloy that is not doped with hafnium, producing a part from the superalloy, and forming a layer of hafnium having a thickness between 50 nm and 800 nm directly on the part. Including a continuous process comprising depositing, forming a mutual diffusion layer on the surface of the component by performing a diffusion treatment of hafnium, thereby obtaining a component made of a nickel-based single crystal superalloy containing hafnium. It should be noted.
