Abstract
We have developed a rapid non-steady anodization technique that leads to an in-situ auto-thinning of the barrier layer due to a space charge limited condition that modifies the local fields at the interfaces of the Al-Al(2)O(3)-electrolyte ternary system. Unlike steady-state growth, in this non-steady case an unequal movement of the boundaries of barrier takes place which etches the electrolyte-oxide interface more than the oxide grows at the oxide-metal interface, leading to a thinner barrier layer and favouring its complete removal via wet-etching process.
