A root bushing for a blade root of a wind turbine rotor blade, a blade root, a wind turbine rotor blade, a wind turbine and a method for manufacturing a root bushing

摘要

A root bushing (9) for a blade root (8) of a wind turbine rotor blade (5), comprising a bushing body (10) and a corrosion protective layer (15), wherein the corrosion protective layer (15) is provided on a face (14) of the bushing body (10) and wherein the corrosion protective layer (15) is applied to the face (14) in a cold-deforming process.;This has the advantage that due to the fact that the corrosion protective layer is applied in a cold-deforming process, the application of the corrosion protective layer does not influence the mechanical properties of the material of the bushing body.
