Corrosion is a natural process that occurs when metals, like iron or copper, react with their environment, leading to deterioration. This often happens when metals are exposed to moisture, air, or chemicals, causing them to break down over time. A common example of corrosion is rust, which forms on iron when it reacts with oxygen and water. Preventing corrosion is important to maintain the integrity of structures and objects. Techniques such as applying protective coatings, using corrosion-resistant materials, or employing cathodic protection can help slow down this process. By understanding corrosion, we can better protect our infrastructure and everyday items from damage.
