Enhancing aluminum corrosion in water

Original paper


For small particles of aluminum (<60 μm), a measurable percentage of the aluminum (>5%) is observed to corrode before passivation occurs at moderate temperatures (>50 °C) in de-ionized water within 1 h. Ball-milling of the aluminum powders with aluminum oxide or water soluble salts results in a significant increase in both the rate of corrosion and the extent of corrosion before passivation. The resulting release of hydrogen gas is of commercial interest for portable hydrogen supply systems. This paper investigates the effect of temperature increase, pH shift, and change of surface area during milling, on the corrosion rate of aluminum powders in water.
