Microstructure and Performance of Antibiofouling Coatings on High-Strength Steel Substrates Immersed in the Marine Environment

High-strength naval steel panels were coated by spraying with five commercial antifouling paints. The first set of specimens was subjected to electrochemical measurements and the anticorrosion properties paints evaluated under controlled laboratory conditions. A second series samples statically exposed for nine months in thirteen different harbors, located Mediterranean Sea Atlantic Ocean, where their in-field efficiency determined. corrosion performance obtained provides predictions that best match fouling protection observed at field sites. results indicate corrosion’s resistivity values determined a good agreement level examining sea samples. reported complementary data show are representative sea-field conditions confirm originality proposed approach, which might lead development innovative low-drag coatings hulls ships, vessels, speed crafts.
