Paper Abstract

Despite the fact that oxidation processes have been studied for a long time, there are still difficulties in knowing what happens in the initial stages of the oxide film formation over non-optical (i.e.rough) surfaces. That is partly due to the lack of sensitivity of present methods, namely the quartz microbalance and the measurement of electrochemical potential, for detecting the presence of very thin layers of oxide [1,2]. Other existing methods are either unsuitable for in-situ measurements [3] or need polished surfaces [4]. The study of the initial oxidation stages can be of utmost importance given the fact that in many situations most of the oxide film forms in the very first moments of the reaction [5].
