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.

Sacrificial anodes are used to protect metal structures from corroding. Sacrificial anodes work by oxidizing more quickly than the metal it is protecting, being consumed completely before the other …

Jul 19, 2024 · What Does Sacrificial Anode Mean? Sacrificial anodes are easily corroded materials deliberately installed in a pipe or tank to be sacrificed to corrosion, leaving the rest of the system …

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 the structure …

Jan 3, 2025 · In simple terms, sacrificial anodes are blocks or rods made from highly active metals such as zinc, aluminum, or magnesium. These metals are more reactive than the metal they are …

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 dramatically slow down …

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 more critical …

Oct 4, 2025 · In marine environments, sacrificial anodes protect boats and ships. They are attached to hulls, propellers, rudders, and engine components to guard against the corrosive effects of saltwater. …

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 metal.

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 magnesium, …
