As object of comparison the finitenesses skin of the person has been considered. It is exposed to the greatest contact loadings and friction during physical activity. For thousand years of evolution the palms skin of the person should adapt to protection against damage and wear. As a result of carried out scanning research it is established, that parameters geometrical structures of a skin of finitenesses in the majority coincide with optimum parameters of a microrelief of technical surfaces.endiscrete surfacesregular profilewear resistancelubricationpalms skinpapillar linesСтаття
