What is it about?
In this publication, we unravel the puzzle of vanadate speciation in aqueous solutions and its effect of aluminum alloy corrosion inhibition.

Why is it important?
With this paper, we challenged the contemporary understanding of the aqueous vanadate system and the influence of the plurality of vanadate species in corrosion inhibition of aluminum alloys.
Perspectives
This publication marks an inflection point in aluminum alloy corrosion inhibition research by chromate alternatives. We found that metavanadates dramatically reduced the oxygen reduction reaction kinetics. Metavanadates were, indeed, as efficient as hexavalent chromium species in inhibiting pitting corrosion of aluminum alloy AA2024-T3. In contrast, decavanadates were not only ineffective but deleterious.
