“…(Frauches-Santos, Albuquerque, Oliveira, & Echevarria, 2014) [12] . The combination of corrosion due to pH and salinity with erosion accelerates the wear of metal structures (Fundão et al, 2017) [13] 2) TYPES OF SALTWATER WEAR According to Moreno, Bonilla, Adam, Borrachero, & Soriano (2015) [14] and Rodriguez (2018) [15] , the main type of corrosion that occurs in saltwater is electrochemical corrosion, shown in Figure 2, which is the conduction of electric current in saltwater, attracting the electrons of the external metal ions, which causes the degradation of the material. There is also anaerobic corrosion, caused by the action of bacteria.…”

This paper is a literature review of coatings that aim to reduce corrosion in metallic pipelines that are in contact with saltwater. Among the existing coatings, the most common and ecologically available ones are: asphaltic enamel (AE), epoxy resin, Fusion Bonded Epoxy (FBE), Neoprene and multilayer coatings (polyethylene-PE, polypropylene-PP and polyurethane-PU). Due to the need by the industries, new technologies in this field are being developed. Carbon nanotubes, DLC (diamond type carbon), and self-recoating coating are some of the new coatings that are in evidence due to their hydrophobic property. There are many industrial applications that require high resistance to saltwater corrosion, such as coastal factories, onshore and offshore platforms, tidal power plants, and water desalination, which justify researches of new technologies in this area.
