Estimation of corrosion parameters in electrochemical systems using Michelson interferometry

This work presents how performance of a simple Michelson interferometric configuration, allows monitoring of oxide layers growing in aluminium structures during preliminary states of oxidation processes in aqueous solutions, without any physical contact with the sample. The alternative experimental arrangement introduce a more simple alignment compared with preliminary proposals, and the obtained interferograms offer a qualitative and quantitative interpretation of important physical parameters related to specified corrosion processes. Finally, a potential improvement in order to obtain monitoring of samples through turbid solutions is discussed.
