Description
о - поверхностное нат жение на границеo - surface tension at the boundary
раздела электролит - газ; 6 - краевой угол на границе электрод - электролит - газ.section electrolyte - gas; 6 - boundary angle at the electrode - electrolyte - gas interface.
Излестно, что при катодной или анодной пол ризации электрода увеличиваетс зар д двойного электрического сло , возрастает смачиваемость электрода электролитом, краевой угол резко уменьшаетс и в соответствии с равенством (I) сила F снижаетс . Таким образом , пол ризаци электрода-инструмента приводит к уменьшению силы сцеплени газовых пузырьков с металлом и, следовательно, к лучшей очистке МЭП от водорода во врем паузы между импульсами. Пол ризаци электродов напр жением ниже потенциала разложени электролита позвол ет проводить промывку МЭП без протекани электрохимических процессов. Увеличение степени очистки МЭП от газообразного водорода позвол ет увеличить продолжительность имнулыса, что приводит к повышению производительности процесса. Кроме того, пол ризаци электродов позвол ет снижать величину МЭЗ, что повышает точность копировани .It is well-known that with cathodic or anodic polarization of the electrode, the charge of the electric double layer increases, the wettability of the electrode with the electrolyte increases, the contact angle sharply decreases and, in accordance with equation (I), force F decreases. Thus, the polarization of the electrode tool leads to a decrease in the adhesion force of gas bubbles with the metal and, consequently, to a better cleaning of the MEP from hydrogen during the pause between pulses. Polarizing the electrodes with a voltage below the potential for the decomposition of the electrolyte allows flushing of the MEP without electrochemical processes. An increase in the degree of purification of MEP from gaseous hydrogen makes it possible to increase the duration of immunule, which leads to an increase in the productivity of the process. In addition, the polarization of the electrodes makes it possible to reduce the magnitude of the MEA, which improves copying accuracy.
Электрохимическую обработку предлалаемым способом провод т следующим образом.The electrochemical treatment by the proposed method is carried out as follows.
Прокачива электролит через МЭП, включают импульсный источник питани . В паузе между импульсамИ на электроды подают посто нное напр жение ниже потенциала разложени электролита (около 1 В). Это напр жение можно подавать как от основного источника питани , так и от дополнителыного (маломощного ). В последнем случае цепи от обоих источников должны быть разв заны, на пример, с помощью полупроводниковых диодов.Pumping the electrolyte through the MEP, include a pulsed power source. In the pause between pulses, a constant voltage below the decomposition potential of the electrolyte (about 1 V) is applied to the electrodes. This voltage can be supplied both from the main power source and from the additional (low-power) one. In the latter case, the circuits from both sources must be separated, for example, using semiconductor diodes.
