Abstract

The study of the geometric characteristics of the metal sheet surface with textured polymer coatings is justified by their connection with mechanical and optical properties. Studying of the surface of coated samples using optical microscopy revealed that it consists of grooves that are assembled into star-shaped clusters scattered across the entire surface of the sheet. At first glance, it seems that these defects are arranged randomly. However, resultats of the production tests showed that the type of defects depends on conditions of formation of the polymer coating. A Method for the constructing a geometrical feature of the surface relief of the polymer coating is proposed. The surface in our model is represented as an array of the clusters of interconnected fractal objects. The surface formation is simulated of completed by the method of random walks.
