✦ Synopsis

Ahatract -The composite oxide film (hydrous + anodic) formed on aluminum foil was chemically stripped to remove only the outer hydrous layer. Ellipsometry of the remaining barrier film showed it to be thinner and have a higher refractive index than conventional anodic barrier films grown to the same voltage. Reanodization to improve film stability gave a further increase in refractive index which indicated that the barrier film had contained some voids. The barrier film is almost entirely crystalline y-Al,O, and the higher field strenplth compared with conventional amorphous anodic films on aluminum is believed to be a character&&c of the denser oxide.

The mechanism of plating on anodized aluminum was investigated . Porous anodic films were formed on 1100 aluminum and the electrochemical behaviour of a number of test reactions (Ag\*/As, Cur'/C,4[Fe(CN) 6 ]Β° /[Fe(CN)6]3 -and QH 2 /Qwas determined .
