A phenomenological model has been developed to describe the build-up formation and to study the stability conditions of a uniform growth of the build-up layer. Based on suitable approximations, analytical formulae have been derived allowing to evaluate the stability region in the concentration-temperature plane depending on the initial roughness of the growing surface.
