In this work, fractal characterization of surface topography is applied to the study of contact mechanics between two coating film rough surfaces. Incorporating with MB model, the occurrence of elastic-plastic transition regime and the hardness effect of coating film are considered in the new contact model. Results show that the real contact areas predicted by this new model are larger than those predicted by MB model. For low fractal roughness parameter and fractal dimension of 1.5, up to 19% of difference can be found between the results from the new model and old model.
