Abstract
It is disclosed a bond or overlay MCrAlY-coating for the use within a high temperature environment for the protection of the base alloy of turbine blades and vanes. The MCrAlY-coating having a γ or γ/γ'-structure comprises a dispersion of β-NiAl and/or γ/β-MCrAlY particles. This provides a reservoir of aluminum reservoir to coatings wherein the reservoir replenish the aluminum lost due to oxidation and interdiffusion during service. The β-NiAl and/or γ/β-MCrAlY is the aluminum reservoir and is applied by mixing appropriate powders with γ or γ/γ′ powders.
