On
the other hand, EDX analysis revealed that there is no distinct composition difference for the dark
and gray strip like phase within the dendrite, with a slightly more Al in the darker area and slightly
more Ti in the lighter area.

According to Kataoka et al., [11] if the Kratky plots present a plateau (which is the case) the particles
most probably are fibrillar.

The corrosion products are composed of Mo, P, Al and O.
The chemical composition of these layers was following: P, Mo, probably Al and O.
Li et. al proposed the mechanism of the corrosion inhibition of aluminum in the studied system [17].
