Abstract
A turbomachine blade () includes a blade body () and a corrosion and erosion protective multilayered coating () bonded thereto, the multilayered coating () including an erosion resistant first layer () at least covering a corrosion and erosion critical area () of the blade body () and a sacrificial second layer () provided over the first layer () at least covering the first layer (), preferably covering the blade totally. A method of manufacturing such a turbomachine blade includes 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 depositing the sacrificial second layer over the first layer at least covering the first layer.
