The turbine has blades (14) fitted co-axially with the rotor in the form of a scoop blade (15) with a platform (16) at one end, A protective layer (18) is applied to the scoop blade and platform on the outside, where hot gas flows round them. There is an expansion gap (20) between the adjacent blades. At least one protective layer projects into the expansion gap.
