  1. Galvanic anode - Wikipedia

    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.

  2. Sacrificial Anodes - American Galvanizers Association

    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 …

  3. Sacrificial Anode - Chemistry LibreTexts

    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 …

  4. Sacrificial Anodes: A Guide To Marine Corrosion Protection

    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 …

  5. How does a sacrificial anode work - CORROSION

    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, …

  6. Sacrificial Anode - Corrosionpedia

    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 …

  7. How Sacrificial Anodes Work in Galvanic Cathodic Protection

    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.

  8. How Do Sacrificial Anodes Work? - boatsgeek.com

    May 22, 2025 · Sacrificial anodes, also known as galvanic anodes, are highly reactive metal components designed to corrode preferentially, protecting a less reactive metal structure from …

  9. The Science Behind Sacrificial Anodes in Corrosion Prevention

    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 …

  10. The basic principle of cathodic protection using sacrificial anodes is the electrochemical cell. As in the case of impressed current cathodic protection, high energy (potential) electrons are forced to flow …
