Turbinenschaufel

摘要

The invention relates to a turbine blade with a corrosion-resistant protective coating of MCrAlY. The aim of the invention is to provide a turbine blade on which the top coating is not subject to spallation. This aim is attained in that the surface layer of the protective MCrAlY coating consists, to a depth of 5 - 50 mu m, of a single-phase alloy in a large area spread evenly over the entire surface layer, where the single-phase alloy is obtained by remelting with a pulsed electron beam.
