| description | Electric conductivity of vapor-gas envelope in electro-impulse polishing mode is closely connected with mechanisms of physical and chemical processes occurring on an anode surface and in pre-anode area of electrolyte, metal removing, smoothing-out of surface profile irregularities and technological regimes influencing on productivity and processing accuracy. The paper presents experimentally substantiated conceptual model of a mechanism for electric conductivity of vapor-gas envelope. According to the model an electric current passing in the envelope and having quasi-constant and high-frequency components is provided by ionic conductivity in electrolyte envelope-enclosing bridges and ionic conductivity in gas envelope phase. It has been shown that quasi-constant of the current component represents a composition of electric current consisting of overlapping time current impulses from electrolyte bridges that enclose the envelope with frequency of 0.01−0.90 kHz and current in a gas phase of the envelope. High-frequency current component is pre-conditioned by ionic conductivity in bridges that commutate the envelope with frequency of 2.5 MHz. The paper theoretically substantiates excessive electrical conductivity of electrolyte in the electrolyte bridges. It has been demonstrated that formation of vapor-gas envelope and its renovation are connected with thermal burst mechanism for destruction of electrolyte bridges. Envelope vibration and hydrodynamic flows within the electrolyte occur due to impulse wave impact on electrolyte layer which is on the border of the envelope. The waves are caused by burtsts of electrolyte bridges and cavitation bubble collapse in pre-anode electrolyte area. |
