Fractal parametrization in erosion process and surface investigation received by electrospark modification

[摘要] High-energy metal surfaces processing by electrospark modification (ESM) leads to formation of the difficult structural state of work materials in non-equilibrium thermodynamic conditions by the self-organizing laws. The article deals with the fractal geometry approaches for a quantitative assessment of the erosion processes by using ESM and the surface structure states after treatment. The authors determine the synergies between fractal dimensions of the surface structures, received by ESM of steel, and their physical and mechanical properties. They point out the surface formation with the maximal gauge, microhardness and durability in the case of definite energy of a spark impulse. In this condition, the fractal dimension of structures is maximum too.
