Abstract
A blade for a turbine engine includes an aerodynamic airfoil extending radially outwards, a blade tip, a blade root, and a platform connected to the root by an upper end. A maximum radial distance between the blade tip and the platform defines a maximum extent of the bearing surface of the airfoil. The blade is partially covered by a protective strip to combat oxidation and corrosion. The strip extends between a lower limit situated on at least one portion of the platform and an upper limit situated on the blade root. The blade tip is not covered by the protective strip.
