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.

sacrificial anode

n
(Metallurgy) metallurgy an electropositive metal, such as zinc, that protects a more important electronegative part by corroding when attacked by electrolytic action
