Abstract:
According to the method, a blade is provided having at least one base for a rim at its free end, and the projecting portion of the rim is built up by depositing successive layers on the base by performing the following steps: activating a laser source connected to an optical head focused on a point of the surface of the top of the base and activating a powder source connected to a spray nozzle, whereby a localized melt is formed at said point, into which the powder is injected, thereby forming a localized region of extra thickness; and aiming the optical head and the nozzle on another point adjacent to said region of extra thickness and returning to the preceding step until a layer has been formed over substantially the entire base.
