This article discusses the process of developing an ultrasonic method of measuring the state of the electrolyte in the process of burning discharge with an electric electrode. The classical methods of electrical effects on the surface of steels, such as electrochemical, electro-erosion, electro-thermal and electro-mechanical have their drawbacks. Namely, high energy consumption, environmental pollution, the problem of recycling by-products, the difficulty of obtaining the required surface profile to a certain extent. In this regard, there is an acute issue of the development and research of new energy-saving, environmentally friendly and cost-effective methods of impact on the surface. At the moment there are no systematic experimental studies of discharge in multiphase media. Not the conditions for the ignition of the discharge with an electrolytic cathode. Not studied physical processes on the boundary of the plasma and the liquid. There is no mechanism of the effect of discharge in the vapor-gas bubble on the surface of metals. All the above reasons delay the development of technology of plasma-electrolyte formation of the surface microrelief. The aim of the work is to measure and optimize the ultrasonic signal and calculate the frequency spectrum of reflected ultrasonic vibrations from a large number of reflectors (electrolyte bubbles), as well as the development of mathematical modeling of the process of reflection of ultrasound from the electrolyte bubbles.
