Aluminum Alloy as Sacrificial Anode for Corrosion Protection: A Review
Abstract: Aluminum sacrificial anodes are widely used for cathodic protection in marine, offshore, and energy applications due to their light weight, high current efficiency, and favorable electrochemical potential. Pure aluminum, however, rapidly passivates in seawater, reducing protective performance. Alloying with elements, such as zinc, indium, gallium, tin, and bismuth, improves activation, ensures uniform dissolution, and stabilizes long-term behavior. This review examines the influence of alloying elements on electrochemical performance, microstructure, and …
