Abstract (en)
[origin: WO2017028912A1] According to the invention, the use of a polymer coating (25) in the carrying flank region (24) minimizes damages. Moreover, a long-term separating effect between the components, e.g. rotor blade and rotor disk, is ensured. According to the invention, the rotor disk groove can alternatively also be coated in whole or in part.
