What is metal corrosion primarily described as?

Metal corrosion is primarily described as the decay of metals through oxidation. This process occurs when metals react with oxygen, moisture, and other environmental elements, leading to the deterioration of the material. Oxygen from the atmosphere or water is often a key factor; it interacts with the metal, causing it to lose electrons and form oxides or other corrosion products. Common examples include rusting in iron, where iron oxide forms due to its reaction with moisture and oxygen.

Understanding corrosion is crucial for maintaining the structural integrity of metal components, especially in environments that may accelerate the process, such as coastal or industrial settings. Preventative measures against corrosion, including coatings, anodizing, and the use of corrosion-resistant materials, are essential for extending the lifespan of metal parts in various applications.
