| 1. | So manufacturers offer another line of defense, called a sacrificial anode rod.
|
| 2. | Galvanic corrosion is often prevented by the use of sacrificial anodes.
|
| 3. | The answer to that would be a sacrificial anode somewhere in the system.
|
| 4. | The sacrificial anodes and cathodes can be of the same or of different materials.
|
| 5. | See the related Sacrificial anode for corrosion prevention.
|
| 6. | It is an electrochemical corrosion a copper-silver galvanic cell forms and the copper acts as sacrificial anode.
|
| 7. | Galvanic or sacrificial anodes are made in various shapes and sizes using alloys of zinc, magnesium and aluminium.
|
| 8. | Galvanic or sacrificial anodes are made in various shapes and sizes using alloys of zinc, magnesium and aluminum.
|
| 9. | Water heaters have a component called a sacrificial anode rod that is suspended in the water inside the tank.
|
| 10. | To slow this process down, water heaters have a replaceable sacrificial anode rod that corrodes instead of the steel.
