Corrosion prevention techniques are methods used to protect materials, especially metals, from deteriorating due to chemical reactions with their environment. Common techniques include applying protective coatings, such as paint or galvanization, which create a barrier between the metal and corrosive elements like moisture and oxygen. Another effective method is cathodic protection, where a sacrificial anode, often made of zinc or magnesium, is attached to the metal structure. This anode corrodes instead of the protected metal, extending its lifespan. Regular maintenance and inspections also play a crucial role in identifying and addressing corrosion early.
