Jan 01, 2011  This diagram indicates the theoretical conditions under which aluminium: (1) should corrode (forming Al 3 + at low pH values and AlO 2 at high pH values), (2) becomes passive due to the presence of a hydrargillite film, i.e. Al 2 O 3.3H 2 O (at near-neutral pH values) and (3) is immune to corrosion (at very negative potentials).
