What is the anode made out of?

The anode is made of Tungsten, the metal with the highest melting point, and also what lightbulb filaments are made of. The cathode also is tungsten, but has a radioactive coating to increase electron emission.

Moreover, how does a sacrificial anode work?

One type of cathodic protection system is the sacrificial anode. The anode is made from a metal alloy with a more "active" voltage (more negative electrochemical potential) than the metal of the structure it is protecting (the cathode). Sacrificial anodes generally come in three metals: magnesium, aluminum, and zinc.

What is used as a sacrificial metal?

A sacrificial metal is a metal used as a sacrificial anode in cathodic protection that corrodes to prevent a primary metal from corrosion, galvanization or rusting.

What is a sacrificial anode and how is it used?

Sacrificial Anodes are highly active metals that are used to prevent a less active material surface from corroding. Sacrificial Anodes are created from a metal alloy with a more negative electrochemical potential than the other metal it will be used to protect.
