sacrificial anode

n.
An anode attached to a metal object, such as a boat or underground tank, to inhibit the object's corrosion. The anode is electrolytically decomposed while the object remains free of damage.

Then, we proposed the combined corrosion protection method of the nitrite penetration and the galvanic anode. Namely, in the method, a galvanic anode process was applied to steel bars by the use of zinc wires until sufficient amounts of nitrite ion reached the steel bars situated at inner positions.
This is the first time that electrodeposition technology using the galvanic anode system to continuously supply electricity has been applied to coral propagation.
Among the products listed are galvanic anode solutions, impressed current solutions, Polatrak CP monitoring systems and pipe-support systems.
Mears has built a galvanic anode system, which can be hooked up using magnesium anodes.
Impressed current CP systems generally operate at higher current and driving voltage levels than galvanic anode CP systems.
Mears has built a galvanic anode system which can be hooked up using magnesium anodes.
A key feature of the laminated zinc tape is its electrically conductive adhesive which, as well as securing the tape to the steel substrate ensures a positive electrical connection to the zinc so that it can act as a sacrificial galvanic anode.
If a galvanic anode system is being used for electrical grounding, a special circuit is required to measure galvanic DC current.
