Rusting is referred to as corrosion by How Stuff Works

How to get rust off knives is a million-dollar question to ask. But what is the need of this question to ask so frequently, the answer is corrosion.

Corrosion is an electrochemical process that involves an anode (a metal object that readily gives up electrons), an electrolyte (a substance that facilitates the movement of electrons), and a cathode (a piece of metal that readily accepts electrons). 

The electrolyte aids in supplying the anode with oxygen when a piece of metal corrodes. Electrons are released as the metal and oxygen mix. The metal of the anode is swept away by the electrical flow or transformed into metal cations in a form like rust as they move through the electrolyte to the cathode.
