Abstract
For various types of surfaces, such as rough surfaces, coatings, and interfaces, there is a need for morphological characterisation and modelling. Morphological properties of surfaces obtained from image analysis techniques can be used to provide quantitative data on surface topography, including size distribution of peaks and valleys, connectivity, geodesic properties, and statistical properties. Several types of surface modeling are introduced: the generation of random surfaces reproducing the textures of rough surfaces by means of random function models imitating some physical process, for which probability properties can be determined; the generation of surfaces by combining surface morphology and simulation of surface evolution during a deformation process (shot peening, indentation); and the generation of coating layers from lattice-gas models which reproduce the deposition of particles on to a substrate.
