Description
Summary:In order to optimize the structure and properties of tool steel, it is necessary to take into account the effect of the self-organization of a dissipative structure with fractal properties at load. Fractal material science researches the relationship between the parameters of fractal structures and the dissipative properties of tool steel. This article describes the application of fractal dimension in robot laser-hardening specimens. By using fractal dimensions, changes in the structure can be determined because the fractal dimension is a present indicator of the complexities of the sample forms. By researching the fractal dimensions of the microstructures of the hardened specimens, people could better understand the effects of the parameters of robot cells on the material. The authors show the experimental results and an analysis of those fractal patterns that occur during robot laser hardening with the different parameters of temperature and speed. Finally, they present the relationship between the fractal dimensions and the parameters of temperature and speed of robot laser hardening.
