The main difference between corrosion and oxidation is that corrosion happens chiefly on metal surfaces whereas oxidation can happen anywhere. In this approach, called cathodic protection, a more reactive metal such as Zn (E° = −0.76 V for Zn 2 + + 2e − → Zn) becomes the anode, and iron becomes the cathode.
