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

Abstract

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 are provided herein. A root bushing for a blade root of a wind turbine rotor blade, having a bushing body and a corrosion protective layer, wherein the corrosion protective layer is provided on a face of the bushing body and wherein the corrosion protective layer is applied to the face in a cold-deforming process is provided herein. 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.
