摘要：
Dissolution behaviour of aluminium-iron alloy has been studied by weight loss and potentiostatic techniques at 30 +/- 0.5-degrees-C. The corrosion rate increases with acid concentration, immersion period and temperature. Effect of some metal ions (Cu2+, Zn2+,. Cr3+, Mn2+, Na+, K+ and Mg2+) has also been studied in 1.00% orthophosphoric acid. All the metal ions except Cu2+ stifled the dissolution of aluminium and the inhibition efficiency increased on increasing the metal ion concentration.
