Abstract
A solution flow‐type micro‐droplet cell with co‐axial dual capillary tubes (Sf‐MDC) was applied to form porous‐type anodic alumina film with layered structure at selected areas on aluminum. The anodizing process with different repetition numbers, yielding different oxide layer numbers, was performed with the Sf‐MDC. The investigation of cross sections of the formed oxide showed that the pore diameter widened at the boundary between layers. From a simulated anodizing process with the Sf‐MDC, the reason for this modification of the pores was suggested to be intermittent anodizing with processes of drying up of the solution of the pores and widening at the bottom of the pores.
