A mechanism for the formation of porous anodic oxide films on aluminium
T.P. Hoar,N.F. Mott +1 more
TL;DR: In this paper, it is shown that in order to account for the formation of porous anodic oxide films on aluminium, it is necessary to assume that oxygen as well as aluminium is capable of diffusing through the compact part of the film.
