  1. Rust is the result of the electrochemical process of corrosion. This occurs when a piece of metal reacts with a liquid and iron oxide, or rust, is produced. To create rust, you need an anode, a metal that releases electrons; electrolytes, liquids that move electrons; and cathodes, metals that accept electrons. The metal in your car can serve as both anode and cathode. As electrons flow via the electrolytes, the metal corrodes and weakens.
