Corrosion is a natural process that occurs when metal surfaces come into contact with various elements, such as water and oxygen.

This can cause damage to the metal over time, leading to the need for costly repairs and maintenance.

In order to prevent corrosion and prolong the service life of metal surfaces, two main technologies are used: impressed current cathodic protection (ICCP) and sacrificial anodes. In this article, we will take a closer look at both of these technologies, their advantages and disadvantages, and when they are best suited for use.


Impressed Current Cathodic Protection (ICCP):

ICCP systems work by applying a small electrical current to a metal surface, which creates an electrolytic reaction that neutralizes the corrosion-causing agents in the surrounding environment. This allows for the prolonged service life of metal surfaces, as well as reduced maintenance costs and increased safety.


Advantages of ICCP include:

  • Prolonged service life of metal surfaces
  • Reduced maintenance costs
  • Increased safety

Disadvantages of ICCP include:

  • Higher initial cost of installation
  • Complexity of system and maintenance


Sacrificial Anodes:

Sacrificial anodes are metallic pieces that are used to protect metal surfaces from corrosion by corroding preferentially to the metal surface that is being protected. As the anode corrodes, it releases electrons which neutralize the corrosion-causing agents in the surrounding environment.


Advantages of Sacrificial Anodes include:

  • Lower initial cost of installation
  • Simplicity of system and maintenance

Disadvantages of Sacrificial Anodes include:

  • Need to periodically replace the anodes
  • Limited protection, since they will be corroded over time



Both ICCP and sacrificial anodes are effective solutions for preventing corrosion of metal surfaces. ICCP systems are more complex and require a higher initial cost, but offer a longer service life for metal surfaces and increased safety. Sacrificial anodes are a simpler and more cost-effective solution, but require more frequent maintenance and offer limited protection over time. The choice between the two will depend on the specific needs and requirements of the application.
