Abstract (en)
[origin: WO2008116757A2] A turbomachine blade (1 ) comprises a blade body (2) and a corrosion and erosion protective multilayered coating (1 1 ) bonded thereto, the multilayered coating (1 1 ) comprising an erosion resistant first layer (3) at least covering a corrosion and erosion critical area (5) of the blade body (2) and a sacrificial second layer (4) pro¬ vided over the first layer (3) at least covering the first layer (3), preferably covering the blade totally. A method of manufacturing such a turbomachine blade comprises the steps of providing a blade and depositing the erosion resistant first layer on the blade body so as to cover at least the corrosion and erosion critical area, followed by deposit¬ ing the sacrificial second layer over the first layer at least covering the first layer.
