  What is sacrificial anode cathodic protection?

  What is a sacrificial anode? Sacrificial anodes are made of highly active metal materials and are used to prevent corrosion on less active metal surfaces, such as steel. Its natural potential is more negative than that of the metal being protected, thus replacing the corrosion of the metal it protects, which is why it is called a "sacrificial" anode.
