| Summary: | The main reason for these researches is to solve the problem of intensification of the alloying process by electric sparks by increasing the energy of the electric pulses. In relation to this, the purpose and object of the research is the need to assume a new concept of organizing the alloying process in order to intensify the strengthening of metal surfaces, excluding the negative effects. Among the electrophysical methods of layer formation, a special place is occupied by alloying by electric sparks of metal surfaces, considering the multitude of its characteristic advantages, which are the following: high adhesion of the deposited coatings, the possibility of depositing coatings of any conductive materials, the simplicity of the process and the low consumption of energy for its implementation. The main results are that after the heating in the electrolyte, the cooling takes place in the air, then in the superficial layers of the samples treated in this way residual tensile stresses act. In conclusion, it is important to mention that through the combined processing the properties of the superficial layers and the exploitation characteristics can be controlled. |
