Abstract: In this paper, we propose a model for cell pattern formation in a salt (or oxide) film deposited on a metal surface in contact with an acid solution. It is assumed that surface tension gradients induced by concentration fluctuations are responsible for convective-diffusive processes which determine the salt (or oxide) film morphology. The onset of cellular convection is examined in the framework of linear stability analysis. Model predictions are discussed by computing the cell dimensions for the iron-sulfuric acid system investigated in our laboratory. © 1990 American Chemical Society.
