Influence of vanadium addition on corrosion behavior of high-energy ball milled aluminum alloy 2024

Abstract

The effect of V addition on the hardness and corrosion of aluminum alloy 2024 (AA2024) produced by high-energy ball milling has been investigated. High-energy ball milled alloys exhibited enhanced solid solubility of alloying elements and ultrafine grains. The addition of V improved the corrosion resistance of the AA2024 alloy, which was attributed to the deposition of V on the cathodic particles and therefore decrease in their ability to sustain large cathodic currents.
