  2. 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.

    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 ...

  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. Galvanization - Wikipedia

    en.wikipedia.org/wiki/Galvanization

    Galvanized steel can last for many decades if other supplementary measures are maintained, such as paint coatings and additional sacrificial anodes. Corrosion in non-salty environments is caused mainly by levels of sulfur dioxide in the air. [10]

  6. 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 ...

    A weekend getaway became a nightmare for one couple when biting ants fell from the ceiling onto them as they slept. Here's how to keep it from happening to you.

  8. Anode - Wikipedia

    As an example, an iron or steel ship's hull may be protected by a zinc sacrificial anode, which will dissolve into the seawater and prevent the hull from being corroded. Sacrificial anodes are particularly needed for systems where a static charge is generated by the action of flowing liquids, such as pipelines and watercraft. Sacrificial anodes ...
