Biofouling is one of the most significant problems to the shipping industries, since accumulation of biofoulers on hull increases drag and fuel consumption, as well as reduces the overall hydrodynamic performance of the vessel. Nowadays, contamination in marine ecosystems due to antifouling coatings is increasing, so more control is needed. More environmentally friendly antifouling coatings obtained by thermal spray techniques has been the target of this research. Thermal spray is a green and economical affordable technology to obtain efficient coatings, which allows the reduction of surface treatments and the possibility of increasing the pieces life. Also, this technique has rapid manufacturing systems for depositing the active coating onto any hull substrate. Thickness, superficial roughness and contact angles of obtained coatings were characterized. Moreover, optical microscopy, scanning electron microscopy, energy dispersive X-ray spectroscopy and UV-Vis spectroscopy were used to characterize polymeric nanocomposite coatings. Finally, static tests were done to study the distribution of biocides in coatings, which influences both efficacy, life time and biocide release rate. |
