抄録

The structure of porous anodic films formed on Al-0.5%Si alloys were examined by transmission electron microscopy of ultramicrotomed sections with special attention to the behavior of Si precipitates during anodic oxidation. Si precipitates are incorporated into the porous anodic film growing over aluminum matrix surrounding the precipitates. Incorporation of Si precipitates proceeds in such a manner that the pores in the porous film growing over the aluminum matrix branch to undercut aluminum beneath the precipitates. Some of the branched pores develop even in the direction parallel to the metal surface.
