Corrosion is a natural process that occurs when metals react with their environment, leading to deterioration. This often happens when metals like iron come into contact with moisture and oxygen, resulting in rust. Corrosion can weaken structures, machinery, and tools, making it a significant concern in industries such as construction and manufacturing. Preventing corrosion involves various methods, including applying protective coatings, using corrosion-resistant materials, and implementing proper maintenance practices. Regular inspections can help identify early signs of corrosion, allowing for timely repairs and prolonging the lifespan of affected items, such as bridges and vehicles.
