Abstract

The study of light scattered from changing surfaces (oxidation, erosion, etc.) is of great interest because of its application in aging control of mechanical components. The models presented in this paper are the results of Optics and Laser Lab. studies of rough surfaces by means of light scattering. First, a model for studying the electroerosion process, as a particular case of pitting corrosion, is presented. Second, another model for studying random changes in roughness surface is also presented. The theoretical results are compared with those obtained experimentally. In summary, it is shown that statistics properties of the light scattered by this kind of surfaces can be taken into account as a parameter to analyze these morphological changes.
