Resumo
Anodizing behaviour of AA2198-T851 friction stir weldment and the corrosion behaviour of unpolished and
polished weldments of the alloy have been investigated. Electrochemical and microscopic techniques were
employed in the study. The results revealed that the manufacturing-process induced near-surface deformed layer
significantly affected the corrosion behaviour of the weldment. Thus, the corrosion behaviour of the weldment in
the polished condition (which is the common practice) was different from that of the unpolished one due to the
presence of near-surface deformed layer. Anodizing as a corrosion protection method for the weldment caused
the formation of pronounced non-uniform oxide layer thicknesses across the weld zones. This was because the
weldment oxidized at a higher rate compared with the parent material (PM) due to an increased proportion of Li
in solid solution in the stir zone of the weldment.
