Anti-corrosion refers to methods and materials used to prevent or slow down the deterioration of metals and other materials due to chemical reactions with their environment. This process is essential in protecting structures, vehicles, and machinery from rust and other forms of corrosion, which can lead to significant damage and safety hazards. Common anti-corrosion techniques include applying protective coatings, such as paints or galvanization, and using corrosion-resistant materials like stainless steel. Additionally, cathodic protection is a method that involves using electrical currents to counteract corrosion, particularly in pipelines and storage tanks.
