A galvanic anode, or sacrificial anode, is the main component of a galvanic cathodic protection system used to protect buried or submerged metal structures from corrosion.

One type of cathodic protection system is the sacrificial anode. The anode is made from a metal alloy with a more "active" voltage (more negative electrochemical potential) than the metal of …

Sacrificial Anodes are highly active metals that are used to prevent a less active material surface from corroding. Sacrificial Anodes are created from a metal alloy with a more negative …

Jul 19, 2024 · Corrosionpedia Explains Sacrificial Anode The mechanism of the sacrificial anode protection system is very similar to the reaction mechanism of electrochemical cells. In …

Apr 18, 2025 · Sacrificial anodes, also known as galvanic anodes, are highly reactive metal components designed to corrode preferentially, protecting a less reactive metal structure from …

The more reactive metal (the anode) will corrode preferentially, protecting the less reactive metal (the cathode). In this context, the sacrificial anode, typically made from zinc, aluminum, or …

Oct 23, 2022 · Galvanic anodes (also commonly known as sacrificial anodes) are highly active metals that are used within cathodic protection systems. They effectively prevent or …

A: Sacrificial anodes work by introducing another metal, called a sacrificial anode, which is created from a metal alloy with a more negative electrochemical potential than the protected …

Oct 2, 2025 · At its core, a sacrificial anode is a more reactive metal intentionally placed on top of a metal you want to protect. It is designed to be consumed—or "sacrificed"—to protect the …

The most active metal (zinc for example) becomes the anode to the others and sacrifices itself by corroding (giving up metal) to protect the cathode - hence the term sacrificial anode.
