CORROSION PROTECTING LAYER SYSTEM, CORROSION PROTECTED BEARING COMPONENT AND METHOD FOR PROTECTING A BEARING COMPONENT AGAINST CORROSION

摘要

A corrosion-protecting layer system, e.g., for a bearing component used in a wind turbine, includes a base layer that contains polyurethane, zinc, and vinylphosphonic acid or silane. An intermediate layer is formed on the base layer and contains polyurethane and zinc. A top layer is formed on the intermediate layer and contains polyurethane and micaceous iron oxide. A sealing layer is formed on the top layer and contains polyurethane.
