Abstract
Transmission electron microscopy of plan and sectional views of porous anodic films formed on an Al-1.86%Cu alloy in sulphuric acid have rev ealed the general and local processes occurring during anodic oxidatio n of the alloy matrix and theta' platelets. In particular, the latter give rise to oxygen generation, film cracking, platelet dissolution an d extra porosity in the porous film before re-initiation of anodic oxi dation of the matrix proceeds.
