An Energetic Analysis of Limiting States for the 0,45% Carbon Steel - Siluminum Active System at Mechano-Sliding Fatigue (Back Effect)

Abstract

Mechanical test results for the active system the cylindrical specimen of the 0,45% carbon steel - counter body as a partial liner from siluminum at mechano-sliding fatigue are given. Curves of mechanical fatigue and mechano-sliding fatigue by the criteria of achieving the maximum permissible wear are constructed for this system. The main characteristics of mechano-sliding fatigue resistance for the studied active system are obtained. The values of the required parameters and coefficients for the for the studied active system are defined and the analysis of the obtained experimental results by using the energy criterion of limit states is made. It is shown that the energy criterion permit to describe satisfactorily the state of the active systems which operate at a mechano-sliding fatigue.
