Abstract
A process for repairing a metallic shroud of a gas turbine blade includes a step of removing a portion of an anti-wear layer to a removal depth that is greater than a depth of wear of the anti-wear layer. Further, the process includes a step of leaving a trace of the anti-wear layer to subsist, wherein the trace of the anti-wear layer extends at least in a re-entrant zone of the Z profile of the blade. The process also includes a step of depositing a new layer of anti-wear material on the trace of the anti-wear layer.
