what are the advantages of rusting of iron

Rust is the oxidized form of iron. Normally oxides are more brittle and weaker than their crystalline metal counterparts. Some oxides are beneficial such as Aluminium oxide, which provides a thin durable shell to prevent the metal from getting more corroded. But, rust is both permeable to water and air, meaning air and water can reach the iron metal underneath the rust.

On top of that, rust is less dense than the iron metal so it can force apart adjacent components, just like how ice puts cracks in the sidewalks. So rust has no positive traits for the physical characteristics of the structure.

Rusting is a natural occurrence where iron tends to form a more stable compound in the environment by reacting with oxygen in the air to form an iron oxide.The rusting of iron is more of a disadvantage than an advantage. Rusting forms an iron oxide which is more brittle than the iron.

Following are the advantages of corrosion: i) Layer of protection: A layer of oxide is formed in surface corrosion which protects the inner metal from corrosion. ii) Sacrificial anodes such as zinc is used as a preventive measure to stop corrosion of other metals.
