sacrificial anode in ship

Ships sailing on the ocean enter a tough and rugged world. There are many different things that can damage a ship, but one of the more dangerous is something you can’t see: corrosion. Corrosion is the gradual deterioration and damage of metal by exposure to water or air. It is a very sneaky kind of business because this is over time, and suddenly, a ship could be in trouble. One very important tool to help keep a ship most safe and sturdy is the sacrificial anodes. So SME is hoping to teach young readers about this small but very important tool and how it keeps ships safe.

Did you know that each ship has a special power that helps keep it safe? It's true! This remarkable ability is known as "anodic protection," and results from the use of sacrificial anodes. Sacrificial anodes are small bits of metal (usually zinc, aluminum or magnesium). These small metal pieces are attached to a ship’s bottom, or hull, the main body of a ship that sits in the water. They’re known as "sacrificial" because they’re made to wear out and be destroyed in order to keep the hull of the ship safe and healthy.

How Sacrificial Anodes Prevent Corrosion on a Ship's Hull

Sacrificial anodes are affixed to the vessel and begin to work immediately to protect it. The sea surrounding the vessel is charged with small electrically powerful mini attacks that can be harmful towards the metallic pump components. But when a sacrificial anode is clamped on, it becomes a top target for those menacing charges. Instead of damaging the ship’s metal, the charges target the anode. This slows down the breakdown of the ship, as time goes on, instead of the ship itself, the anode will slowly begin to break down. The anode will gradually corrode away compared to the ship, which is supposed to keep the ship from corroding. It’s almost like a superhero taking a bullet for somebody else, always shielding the ship!
