Corrosion protection refers to methods used to prevent or slow down the deterioration of materials, especially metals, due to chemical reactions with their environment. Common causes of corrosion include moisture, oxygen, and pollutants. Effective protection techniques include coatings, galvanization, and the use of corrosion inhibitors. One popular method is applying a protective layer, such as paint or a polymer coating, to shield the metal from exposure. Another method is galvanization, where a layer of zinc is applied to steel to prevent rusting. Regular maintenance and inspections are also essential to ensure long-lasting protection against corrosion.
