    Aluminum sacrificial anodes (light colored rectangular bars) mounted on a steel jacket structure. Zinc sacrificial anode (rounded object) screwed to the underside of the hull of a small boat. Cathodic protection (CP; / k æ ˈ θ ɒ d ɪ k / ⓘ) is a technique used to control the corrosion of a metal surface by making it the cathode of an ...

  3. Galvanic anode - Wikipedia

    en.wikipedia.org/wiki/Galvanic_anode

    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. They are made from a metal alloy with a more "active" voltage (more negative reduction potential / more positive oxidation potential ) than the metal of the structure.

  4. Sacrificial metal - Wikipedia

    en.wikipedia.org/wiki/Sacrificial_metal

    A sacrificial metal is a metal used as a sacrificial anode in cathodic protection that corrodes to prevent a primary metal from corrosion or rusting. [1] It may also be used for galvanization. Equation

  5. Galvanic corrosion - Wikipedia

    en.wikipedia.org/wiki/Galvanic_corrosion

    Galvanizing with zinc protects the steel base metal by sacrificial anodic action. Cathodic protection uses one or more sacrificial anodes made of a metal which is more active than the protected metal. Alloys of metals commonly used for sacrificial anodes include zinc, magnesium, and aluminium. This approach is commonplace in water heaters and ...

  7. Caustic embrittlement - Wikipedia

    en.wikipedia.org/wiki/Caustic_embrittlement

    Inside the cracks, the water evaporates and the amount of hydroxide keeps increasing progressively. The concentrated area with high stress works as anode and diluted area works as cathode. At anode, sodium hydroxide attacks the surrounding material and then dissolves the iron of the boiler as sodium ferrate forming rust. This causes ...
