  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.

  3. Galvanic corrosion - Wikipedia

    en.wikipedia.org/wiki/Galvanic_corrosion

    In this case, sacrificial anodes work as part of a galvanic couple, promoting corrosion of the anode, while protecting the cathode metal. In other cases, such as mixed metals in piping (for example, copper, cast iron and other cast metals), galvanic corrosion will contribute to accelerated corrosion of parts of the system.

    In 2009, Rheem and Ruud were the first to sell a Hybrid Heat Pump Water Heater, which was more than twice as efficient as similar electric water heaters. [24] Also in the same year, Rheem and Ruud central air conditioners were reported to have the fewest percentage of units requiring repair among all major HVAC brands according to Consumer Reports.

  6. Galvanic series - Wikipedia

    en.wikipedia.org/wiki/Galvanic_series

    The difference can be measured as a difference in voltage potential: the less noble metal is the one with a lower (that is, more negative) electrode potential than the nobler one, and will function as the anode (electron or anion attractor) within the electrolyte device functioning as described above (a galvanic cell).
