Annual costs for corrosion damages are estimated at almost 4 % of gross domestic product (GDP Germany 2017 around 130 billion €).
Steel components, in particular, are subject to continuous weathering due to permanent moisture and intensive UV radiation. Small damaged areas in the coating system can lead to significant corrosive damage very quickly. Offshore turbines, in particular, are subject to continuous weathering due to permanent moisture, high salt corrosion, intensive UV radiation and strong waves.
Continuous maintenance and immediate repair are of immense importance.
