Resumo
The effect of unequal levels of deformation and fragmentation on the electrochemical response of friction
stir welded AA2024-T3 has been investigated using electron backscatter diffraction, scanning electron
microscopy, global and localized electrochemical techniques. The friction stir welding process introduced
unequal distribution and fragmentation of coarse intermetallic particles, such that more clusters of these
particles were present in the thermomechanically affected zone of the weld. This resulted in a higher
susceptibility to severe localized corrosion in this region when compared with the others. Results from
electrochemical measurements using a microcell could not be clearly correlated with the corrosion
behaviour because no significant differences were observed using these techniques. On the other hand,
LEIS and SVET results were in agreement and correlated with the corrosion evolution at the surfaces of
the tested samples.
