Aluminum alloys are popular for their high strength-to-weight ratio, achieved through alloying elements and heat treatments that create intermetallic particles (IMPs) which affect their corrosion resistance.
The review focuses on the electrochemical and galvanic corrosion behaviors of various important intermetallic compounds commonly found in aluminum alloys, detailing specific phases like Q-phase, π-phase, and θ-phase.
It also addresses limitations in studying these compounds, identifies research gaps, and discusses phenomena such as galvanic polarity reversal and the self-dissolution of IMPs.
