Abstract (en)
[origin: WO9955527A2] The invention relates to a product (1), especially a gas turbine blade (1), having a metallic base (2) on which a protective layer (3, 4) is bonded for protecting against corrosion. The protective layer (3, 4) comprises an inner layer (3) made of a first MCrAlY alloy and of an outer layer (4) which is made of a second MCrAlY alloy and which is bonded on said inner layer (3). The second MCrAlY alloy is mainly present in the gamma -phase. The invention also relates to a method for producing a protective layer (3, 4), whereby the outer layer (4) is produced by remelting an area of the inner layer (3) or by depositing an MCrAlY alloy in a liquid phase.
