Cathodic protection is a vital technique employed to safeguard metallic structures, particularly those susceptible to corrosion. Metallic aluminum anodes serve as the cornerstone of this protective measure by corroding preferentially, thus diverting corrosive effects away from the protected structure. In the realm of precious metal artifacts, where

Aluminum anodes provide a sacrificial protection mechanism against oxidation by willingly corroding themselves. This preferential erosion of the aluminum anode prevents the underlying metal from undergoing damaging corrosion. The effectiveness of an aluminum anode is influenced by factors such as the composition of the electrolyte, current density,
