biofilm coatings in addition to the anodization, are used to slow down and protect the corrosion. For instance, the use of painting or enamel protects the material from corrosion by creating a corrosion‐resistant barrier between the damaging environment and the structural material. In this case, the use of chemicals that form an electrically insulating or chemically impervious coating on exposed metal surfaces to suppress electrochemical reactions make the system less susceptible to scrapes or imperfections in the coating because extra inhibitors can be present wherever the metal is exposed. Nowadays, organic and inorganic corrosion inhibitors, whether natural or artificial, are increasingly important. Because of the great importance of them, in this section, the organic and inorganic corrosion inhibitors are presented considering the molecular structures, main characteristics, and environmental effects.
