Typically, metals corrode because they react with oxygen or sulfates, but chemicals are the occasional culprit as well. One of the most common ways to prevent corrosion is by applying a protective coating. This is known as corrosion. Rust is the result of iron oxide. When a material reacts with the external environment, over a time, its structure will be deteriorated, and breaks down into small pieces. The process of weakening of a substance because of electrochemical, chemicals, and many other reactions that occur on the surface of that substance is known as corrosion; on the other hand, the layer that produces on the surface of iron when open to air and moisture is known as rusting. When a piece of metal corrodes, the electrolyte helps provide oxygen to the anode. Rusting is the corrosion of iron which is the most widely used structural metal.
