TURBINE PART OF SUPERALLOY WITH RHENIUM CONTENT AND ITS MANUFACTURING METHOD Russian patent published in 2022 - IPC F01D5/28 

FIELD: metallurgy.

SUBSTANCE: invention relates to a turbine part containing substrate of a monocrystal superalloy based on nickel, containing rhenium, that has a phase y-y’-Ni and an average mass fraction of chrome of less than 0.08, a sublayer covering substrate, made of a metal superalloy based on nickel. In this case, the sublayer of the metal superalloy contains at least aluminum, nickel, chrome, silicon, hafnium and has a phase y’-Ni₃Al in the prevailing volume.

EFFECT: solution is proposed on the effective protection of a turbine part of a superalloy from oxidation and corrosion, while increasing its service life compared to known parts.
