Corrosion inhibitors are substances that help prevent the deterioration of materials, especially metals, due to chemical reactions with their environment. They work by forming a protective layer on the surface of the metal, which reduces the rate of corrosion caused by factors like moisture, oxygen, and salts. Commonly used in industries such as construction and manufacturing, these inhibitors can be applied in various forms, including coatings, additives, and treatments. There are different types of corrosion inhibitors, including anodic, cathodic, and passivating inhibitors. Each type functions differently, targeting specific corrosion mechanisms. For example, anodic inhibitors work by reducing the anodic reaction in the corrosion process, while cathodic inhibitors slow down the cathodic reaction. By using these substances, industries can extend the lifespan of their equipment and structures, ultimately saving costs and resources.
