| It's made of a specially coated material covered with zinc anodes to ward off corrosion. |
| Gaseous hydrogen and oxygen flow separately around either side of two electrolytic plates serving as anodes and cathodes. |
| Our second dive is on this historic submarine, so that Mike can check anodes placed to reduce corrosion of the now-delicate hull. |
| The materials that are useful for anodes must be good conductors and must not corrode too easily under oxidizing conditions. |
| Embedded galvanic anodes are also used to address potential corrosion problems at the joints and for general substructure repairs. |
| The rods serve as negative electrodes, or anodes, and the tube serves as a positive electrode, or cathode. |
