Corrosion control refers to the methods and techniques used to prevent or slow down the deterioration of materials, especially metals, due to chemical reactions with their environment. This process is essential in various industries, including construction, transportation, and manufacturing, to ensure the longevity and safety of structures and equipment. Common corrosion control methods include the application of protective coatings, such as paint or galvanization, and the use of corrosion inhibitors. Additionally, techniques like cathodic protection can be employed, where a sacrificial anode, often made of zinc or magnesium, is used to protect more valuable metals from corrosion.
