WebSep 19, 2024 · Cathodic Protection One way to avoid these problems is to use a more easily oxidized metal to protect iron from corrosion. In this approach, called cathodic protection, a more reactive metal such as Zn (E° = −0.76 V for Zn2 + + 2e − Zn) becomes the anode, and iron becomes the cathode. Webcathodic protection, we must set up a situation where the tank and/or its piping become a cathode. This is accomplished by creating a flow of electrons onto the surface of the metal. The corrosion then happens at the place that is producing the electrons (the anode). The anode will deteriorate over time and will need to camping beauvoir sur niort
