| The cathode in an electrochemical cell is the site where electrons are consumed. For each electron that is produced at an anodic site, an electron must be consumed at a cathodic site. No metal loss occurs at sites that are totally cathodic. | |
| Cathodic protection prevents corrosion by making a metal, which would ordinarily behave like an anode and corrode, behave like a cathode and be free from corrosive attack. In cathodic protection this is achieved by providing electrons of a higher energy level (electric potential) than those which would be produced in the corrosion reaction at the anode. | |
|
The electrons that are produced at anodic sites are consumed at cathodic sites. |
|
| Cavitation corrosion is corrosion that is enhanced through the formation and collapse of gas or vapor bubbles at or near the metal surface | |

|
| Concentration cell corrosion is corrosion that is accelerated by differences in environment between separated areas on a single metal | |
| Corrosion fatigue is the reduced ability of a metal to withstand repeated stress when exposed to the combined action of stress and a corrosive environment as compared to the effects of stress alone | |
| Crevice Corrosion can be thought of as a special case of pitting corrosion, but one where the initial "pit" is provided by an external feature; examples of these features are sharp re-entrant corners, overlapping metal surfaces, non-metallic gaskets or incomplete weld penetration. | |
