sacrificial anode

Also found in: Encyclopedia, Wikipedia.

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.

The single most neglected component of your home's water heater is its sacrificial anode. The anode is a magnesium or aluminum rod that is suspended inside your steel storage tank.
The cathodic protection system of airport apron pipe network generally adopts magnesium alloy sacrificial anode cathodic protection [7], and it also inevitably has an adverse effect on the sacrificial anode performance [8, 9].
Galvanising protects in two ways; it forms a coating of corrosion-resistant zinc which prevents corrosive substances from reaching the more delicate part of the metal and the zinc serves as a sacrificial anode so that even if the coating is scratched, the exposed steel will still be protected by the remaining zinc.
Corrosioncaused by the oxidation of the functional water can be protectedby the sacrificial anode which is made of a metal that is moreeasily oxidized than the dental metals.
But she revealed she has But she revealed she has nicknamed him her "sacrificial anode".
In this study, two types of PV modules were prepared to evaluate the effect of a sacrificial anode. First, 156 mm x 156 mm multicrystalline silicon (Si) solar cells with two bus bars were used and interconnected by Cu wire plated with 62Sn36Pb2Ag solder.
Every tank-style water heater contains a "sacrificial anode rod" to protect the steel tank.

One company's solution to this problem involves condenser coils suspended such that the vibrations of normal operation shake any collected scale loose, wide spray nozzles to prevent blockage by scale, and sacrificial anode rods to prevent coil corrosion.
- The timing belt is made of special durable materials, and sacrificial anode metal in the coolant pathway helps prevent corrosion.
All water heater manufacturers have recommendations that must be followed: check proper operation, drain off' sediment and periodically replace the sacrificial anode rod.
