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 ...
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]
3,000 acquired by Armed Forces of the Philippines in 2017, for issue to all service branches. Majority went to the Philippine Army. [ 101 ] [ 102 ] AFP ordered 60,000 units under AFP 0.45 caliber Hammer Fired Pistol acquisition project, majority expected to go to the Philippine Army.
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]
The Toyota Vios has been the best-selling car in the Philippines from 2008 until 2016, and again since 2018. The Mitsubishi Lancer was considered an automotive icon in the country. Having been built in the country since the first generation up until its last generation in 2017.

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 ...
