Transmission electron micrograph of a barrier-type anodic film formed at 100% efficiency on an AI-10at.%Nd alloy, revealing enrichment of neodymium species in a surface layer of the film. (Herrera-Erazo eta ., 2000). [Pg.148]

Figure 8.3 shows transmission electron micrographs of selected regions of the anodic film located near the surface (Fig. 8.3a), within the film (Fig. 8.3b), and adjacent to the alloy/film interface (Fig. 8.3c). The anodic film reveals a porous morphology, with pores confined within alumina cells the barrier layer is evident beneath the pore base together with the scalloped alloy/film interface. The cell and pore diameters are about 30 and 10 nm, respectively, with a barrier layer thickness of 11 nm. Titania nanoparticles are distributed in a thin, outer layer of several tens of nanometres thickness the particles have diameters up to 10 nm. No particles are evident in the porous skeleton of the anodic film.
