Abstract

The incorporation of metal oxide nanoparticles into a barrier-type anodic alumina film on an Al substrate was investigated using a one-step anodic oxidation combined with electrophoretic deposition. Basically, the electrolysis was carried out in an oxide nanoparticle dispersed ammonium pentaborate solution using an Al substrate as the anode. As a result, the TiO2 and SiO2 nanoparticles with a negative surface charge could be introduced into the alumina film grown on the Al anode, and the film thickness increased by the dispersion of the nanoparticles inside the alumina layer. The measurement of the capacitance and corrosion potential demonstrated that the present method was valid for enhancing the characteristics of the barrier-type alumina film.
