Project Outline
|
The aim of this project is to develop new self-healing coatings for corrosion mitigation of offshore wind turbines. In the atmospheric zone, the lack of continuous electrolyte (seawater) does not allow conventional cathodic protection (CP) systems to be applied as corrosion mitigation method. Therefore, the use of novel coating systems can provide a cost-effective solution to corrosion problem. The novel system comprises two layers. The first layer on the carbon steel is TSZA (thermally sprayed Zn85/Al15) as a sacrificial layer. Due to its active nature and porosity, it corrodes readily so additional paint layer is often used. This layer (epoxy-based) will be enriched with microcapsules loaded with self-healing agent. The new coating system is likely to improve the corrosion mitigation behaviour significantly.
