Paper Abstract

A new imaging process of laser speckle has been proposed especially for characterizing and measuring the change of the surface roughness of metallic samples, as a result of corrosion attacks in aqueous solution. The process could provide useful microscopic information about a preceding corrosion attack, i.e., pitting corrosion, that may take place at the metal surface. In other words, one may predict from this process different kinds of corrosion forms before actually can be detected by the naked eyes. In addition, a correlation between data of surface roughness and corrosion of metallic surfaces can be established based on the proposed process. In the present report, preliminary results on a stainless steel examined in a saline solution are given.
