Abstract
A method is provided for reconditioning a blade of a gas turbine. The blade includes a blade airfoil, with a pressure side and a suction side, which extends in the blade longitudinal direction between a platform and a blade tip, and has a leading edge and a trailing edge, and is outwardly delimited by a pressure-side wall and a suction-side wall which converge at the trailing edge of the blade airfoil, forming discharge openings for cooling air which are arranged in a distributed manner along the trailing edge between the walls.
