Purpose: The goal of this work is the fractal and multifractal characteristics and tribological properties of the TiN and TiN+multiTiAlSiN+TiN coatings obtained by cathodic arc evaporation PVD process on the multi-edge plates made from the Al203 + SiC(w) oxide tool ceramics. Design/methodology/approach: The results of the chemical and phase composition researches, tests of mechanical properties, including thickness, microhardness and roughness were evaluated. The characterized structure and surface topography of analyzed coatings, presenting fractal and multifractal character, was confirmed. To estimate the fractal dimension and multifractal spectra, measurements obtained from atomic force microscope (AMF) images, projective covering method (PCM) was used. Findings: The researches were carried out to confirm that the fractal dimension and parameters, describing the multifractal spectrum shape, may be used for characterizing and comparing coating surface obtained by cathodic arc evaporation PVD process and of the substrate material made from Al203 + SiC(w) oxide tool ceramics. Research limitations/implications: Relationship between parameters describing the multifractal spectrum and physical properties of the examined materials calls for further work. Originality/value: Fractal and multifractal analysis gives possibility to characterise in the quantitative way the extent of irregularities of the analysed surface.
