[0002] Cathodic protection is a commonly used anti-corrosion technology, in which the sacrificial anode is one of its main principles. The sacrificial anode is usually made of a metal with a more active potential. It will be corroded in the electrochemical reaction, thereby protecting the protected metal from corrosion.

[0003] Cathodic protection is generally achieved through aluminum alloy sacrificial anodes, and the aluminum alloy is generally placed on the protection mechanism for consumption. However, due to the strong corrosion of seawater, the aluminum alloy will slowly be consumed. Personnel need to replace the aluminum alloy regularly to ensure the anti-corrosion effect. However, the consumption of aluminum alloy is generally observed and recorded by personnel, and the aluminum alloy cannot be tested at all times. This poses a risk of the aluminum alloy being completely consumed and unable to be anti-corrosion.
