Corrosion is a natural process where materials, usually metals, deteriorate due to various chemical reactions with their environment. This can result in the loss of material, weakening of structures, and ultimately failure of the material. Corrosion can be caused by factors such as moisture, acids, salts, and other chemicals present in the environment. Research in the field of corrosion aims to understand the mechanisms of corrosion, develop methods to prevent or control corrosion, and find ways to protect materials from deterioration. This research area is essential for industries such as construction, automotive, and aerospace, where corrosion can have significant economic and safety implications.
