Fractal dimension in tribology – an overview

Friction and wear in tribological systems are phenomena that can be interpreted on a macroscopic scale. The emergence of micro nano-sized requires the treatment through concept fractals. Thus, to perceive occurring macro-system, it is fundamental think about them at micro-scale nano-scale, center, for case, level hardness atomic composition. This article realizes survey main concepts treating issues terms It clear continuous change nano topography friction surfaces during dynamic functioning various mechanisms processes taking place treated using fractals chaos theory. To this end, concluded all existing theories tribology should adapted include fractal dimension roughness.
