Abstract (en)
[origin: WO2022029393A1] The invention relates to a nickel-based superalloy part (100) comprising: - a nickel-based superalloy substrate (10); and - a metal sublayer covering the substrate, characterised in that the sublayer comprises a first (11) and a second (12) layer, the first layer being located between the substrate and the second layer, the first layer comprising a first γ'-Ni3Al phase and a second γ-Ni phase, the second layer comprising a first γ'- Ni3Al phase, a second γ-Ni phase and a third β-NiAl phase, the average atomic fraction of aluminium in the second layer being strictly greater than the average atomic fraction of aluminium in the first layer.
