| Abstract: | A duplex-film model for barrier anodic films on aluminium is suggested, the lower layer being homogeneous and amorphous and the upper consisting of a dispersion of a crystalline phase in an amorphous matrix. From impedance measurements over a range of frequencies, the dielectric constants of the layers are estimated as 12 and 9 respectively. |
