Modeling of morphological kinetics in general and localized corrosion

Two theoretical methods have been proposed to investigate the evolution of the interface shape. The first one enables to relate the various types of o verall morphological evolution (roughness levelling and increase) and the d riving force intensities to the nature of the physical chemistry occurring at the interface and its neighbourhood. The second one deals with the quant itative characterization of local morphological evolutions, in particular i n stress corrosion. It allows the determination of crack initiation and pro pagation kinetics from morphological information gathered with samples.
