Pitting by corrosion in aluminum and Al-6201 alloy
Keywords:Aluminum, Aluminum alloy, Pitting corrosion, Corrosion, Pitting and repassivation potentials
The susceptibility of pure aluminum and aluminum 6201 alloy to pitting was investigated in sodium chloride solutions through determination of the corrosion, repassivation and pitting potentials. Potentiodynamic polarization including scratching techniques were employed being also determined the type and relative amount of corrosion damage to the metals. The morphology of the attack was determined using scanning electron microscopy (SEM). The results showed a similar performance for aluminum 6201 alloy and aluminum. It was also observed that an increase in chloride concentration resulted in a decrease in the corrosion, pitting and repassivation potentials of both materials.
