# Do the presence of ions facilitate corrosion?

Corrosion is a fundamental redox process; iron can be oxidized to $F e O$ and $F {e}_{2} {O}_{3}$ and other oxides as iron has a particularly rich redox chemistry. Given that corrosion relies on a series of redox processes, electron transfer is GREATLY facilitated by presence of ions. Iron and steel-hulled ships and bridges are routinely inspected in order to slow and prevent structural damage due to such corrosion.
