Surface roughness plays an important role in many physical phenomena, including wave scattering, friction, adhesion, electrical conductivity, capacitance and heat transfer, as well as applications of thin films for sensors. We studied microphotographies of polyester coatings surfaces of metal sheets, and concluded that they are rough ones. Using the scanning probe microscopy method, we investigated the surface texture of these samples and found that the largest number of peaks on the surface has a height in the range exceeding the roughness level, and their distribution on surfaces has a fractal character. We used the method of 2D fractal functions for modeling of surface texture of these samples. The optimal fractal model was chosen on the basis of comparison of the geometrical profiles for polymer coating surface of metal sheet obtained by the opticale microscopy method and calculated on the basis of fractal models.
