Abstract
To enhance the reliability of floating offshore wind platforms exposed to salt-fog environment, a new material, CNTs-MoS2/Cu, was developed for slip rings. Tribo-electrical properties of composites in salt-fog environment were explored. A novel method for characterizing current-carrying stability, based on correlation dimension, was proposed. When compared to copper, the correlation dimension decreased by 31.43%. It reveals that composites exhibit superior current-carrying stability compared to copper in salt-fog environment. The wear mechanism is further revealed. CNTs enhance the damage resistance of friction film, while MoS2 contributes lubrication. The appropriate addition of CNTs and MoS2 leads to the formation of an intact conductive lubrication anti-corrosion film on the surface, reducing the erosive impact of salt fog.
