Anti-corrosion refers to the methods and materials used to prevent or slow down the deterioration of metals due to chemical reactions with their environment. This process is essential in protecting structures and equipment from rust and other forms of corrosion, which can lead to significant damage and safety hazards. Common anti-corrosion techniques include coatings, galvanization, and the use of corrosion-resistant alloys. Various industries, such as construction and automotive, rely on anti-corrosion measures to extend the lifespan of their products. For example, steel structures are often coated with paint or zinc to create a barrier against moisture and oxygen, which are key contributors to corrosion.
