Table 1 and 2 show the results obtained for crevice of Al 6061 couple using the EDS
technique. In the zone A the presence of oxygen is lower than in zone B, and elements of
alloy of Al 6061 appear indicating the presence of the substrate of aluminium. The zone B
mainly corresponds to aluminium oxide.

Al 1050 alloy was analyzed using EDS and the results are shown in Table 3 and 4. It was
possible to identify only Al and oxygen in different percentages depending of the zone
analyzed.
