How Sacrificial Anodes Function

Cathodic protection is the most effective way to protect metal structures from the dangers and catastrophes that corrosion can bring. Cathodic protection relies on sacrificial anodes to function in order to protect structures from corrosion. If you’re curious about cathodic protection, start by learning more about how sacrificial anodes function.

The Materials Used for Sacrificial Anodes

The material used to create a sacrificial anode is essential to the ability of the cathodic protection to repel harmful corrosion to the structure. Pure active metals such as magnesium or zinc are best for use as sacrificial anodes, although sometimes, you can use an aluminum alloy that’s tailored to use for this specific purpose.

What a Sacrificial Anode Is

Highly active meals are applied to a metal surface to protect that structure from corroding. It is called a sacrificial anode because that anode is sacrificed for the sake of the structure as a whole. It is consumed by corrosion in place of the structure.

How They Are Applied

Sacrificial anodes are applied to the protected structure through a process involving welding or making mechanical connections with low resistance. It’s also important to insulate the connections. The strength and low resistance connections allow the anodes to be consumed in place of the structure, enabling cathodic protection to function correctly.

Industries Using Cathodic Protection

There are many industries that utilize cathodic protection to protect their structures. Here are a few examples:

  • Pipelines
  • Ships
  • Tankers and tank structures
  • Docks
  • Infrastructure such as bridges

There are many other industries that benefit from investing in properly executed cathodic protection.
