Corrosion is a natural process that involves the gradual destruction of metal components through chemical or electrochemical reactions that take place between the metal and the environment. The most common kinds of corrosion result from electrochemical reactions, and most metals are easily oxidized, meaning they tend to lose electrons to oxygen (and other substances) in the air or in water. The following are some of the main causes of corrosion:

• Weather conditions: Exposure to environmental elements such as water, wind, and moisture can cause metals to corrode quickly. Rain and exposure to too much sun can also expose metals to corrosion.

• Neglect: Failure to take proper care of metallic objects, from vehicles to tools and machinery, can cause them to corrode quickly. It is important to keep metal objects clean and properly taken care of to ensure they do not corrode.

• Acidic substances: When acidic substances, including water, come in contact with metals such as iron and steel, rust begins to form. Rust is the result of corroding steel after the iron particles have been exposed to oxygen and moisture.

• Stress: Corrosion can also happen when metals like steel are placed under too much stress, causing the material to crack.

Preventing corrosion is crucial for maintaining the longevity and value of metal structures, like bridges and boats. Some ways to prevent corrosion include coating the metal with a protective layer, using corrosion-resistant metals, and keeping the metal dry and free from moisture.
