| Abstract: |
The plasma surface hardening, as one of methods of hardening by the sources of heating with the high density of power, finds presently wide and effective application as in the conditions of boss short-series and single-part (including repair), and large-scale and wholesale manufacture. One of effective methods of research and optimization of the plasma surface hardening is the use of computer simulation. The complex mathematical model of steel parts hardening at the high-speed plasma heating is presented in the article. Model includes mathematical description of steel parts heating and cooling, and also forming of their stress-strain state. The distinctive feature of the presented model is taking into account under modeling of phase transformations and plastic deformations. It allows to achieve the maximally adaptation of the simulation results to real physical characteristics of the process. The algorithm of model computer realization, based on the application of final elements method is offered.
