Corrosion of Iron

The most common type of iron corrosion occurs when it is exposed to oxygen and the presence of water, which creates a red iron oxide commonly called rust. Rust can also effect iron alloys such as steel.

Methods to prevent corrosion

1. Barrier Coatings. One of the easiest and cheapest ways to prevent corrosion is to use barrier coatings like paint, plastic, or powder.
2. Hot-Dip Galvanization.
3. Alloyed Steel (Stainless).
4. Cathodic Protection.
