The paper analyses the corrosion behaviour of naturally and artificially aged
AA2024 alloy in NaCl solution and in the presence of an environment ‐ friendly
corrosion inhibitor, CeCl 3 . On the basis of the values of polarisation resistance
and corrosion current density, the corrosion resistance of the protective
inhibitor film is established as well as the general corrosion resistance of this
aluminium alloy. Resistance to pit formation is determined based on the
difference in pitting and corrosion potentials while resistance to pit growth is
determined based on the amount of charge consumed during pit growth. A
scanning electron microscope is used to examine the morphology of the pits
formed during the pitting corrosion testing, as well as to determine the cerium
content on intermetallic particles and the matrix AA2024 alloy. The corrosion
behaviour of AA2024 alloy is investigated after different test periods in NaCl
solution and in the same soluti...on with the CeCl 3 inhibitor. The corrosion
resistance of both tempers of AA2024 alloy is more than one order of magnitude
higher in the presence of CeCl 3 . An explanation of the observed differences in
the corrosion behaviour of the naturally and artificially aged AA2024 alloy is
proposed. Different corrosion behaviour of the alloy after different test periods
is also explained.
