Formulated research tasks. A mathematical model and analytical dependencies for calculating the energy of the formation of the nucleus of the dislocation taking into account the electrical component are developed. The influence of electrical polarization of a constant and change of voltage to 12 in the spade steels 15x11 mf and 20x13sh to the relative change in their microhardness are revealed. It is established that it depends on both the voltage value and from the effort on the indenter and acquires maximum values in the surface zone, reaching values to 25%. The character of the microhardness of steel 20x13s depends on the polarity of electric voltage. The maximum decrease in microhardness of steel 15x11 mf in polarization with a change in electric voltage 10 V with frequencies of 20 Hz, 200 Hz, 2500 Hz and 20,000 Hz was observed at a frequency of 20,000 Hz and reached 35%. The relative change in microhardness with an increase in the effort on the indenter at a steady electric voltage is the form of a complex field of extreme curve, which resembles fluctuations that undo. The influence of polarization of aluminum alloy D16 with pulsed electric voltage U = 0.2 in and a pulse duration 12 μs with a frequency of up to 1 kHz is investigated. It is established that the largest changes in michardness are observed in a thin surface area. The magnitude of the changes depends on the frequency and effort to the indenter and at a frequency of 711 Hz and reached from + 45% to - 45%. The analysis of the results shows that the subject is relevant and deserves further research, since it affects the fundamental bases of management of mechanical properties of metals at the stage of operation of products Product Description popup.authors popup.nrat_date 2021-04-12 Close
