Применение импульсного тока позволяет во многих случаях получить необходимый эффект более дешевыми средствами и обеспечить дополнительную управляемость электрохимическим процессом за счет регулировки временных параметров импульсов тока, снизить энергетические затраты на процесс полирования и очистки поверхностей по сравнению c обработкой при постоянном токе, повысить эффективность обработки, при которой скорость сглаживания микронеровностей обрабатываемой поверхности, отнесенная к общему съему металла, значительно возрастает. Например, применение биполярных импульсов при полировании многих металлических материалов позволяет отказаться от использования дорогостоящих и вредных хромсодержащих электролитов. Применение импульсного режима при электролитно-плазменном полировании помогает добиться снижения энергопотребления и повышения эффективности процесса при сохранении высокой интенсивности, качества обработки и экологической безопасности. Для исследования влияния временных параметров импульсов тока, а также длительности пауз между ними на характеристики поверхности деталей из различных металлических материалов в процессе электрохимической обработки и при переходе процессов в область электролитно-плазменной обработки при повышении напряжения смоделирован, разработан и изготовлен специальный источник питания, обеспечивающий возможность регулирования частоты, длительности положительного и отрицательного импульсов, а также пауз между ними в широком диапазоне. Разработанный источник питания позволяет формировать импульсы тока до 50 А при напряжении от 0 до 400 В положительной и отрицательной полярностей и способен регулировать их длительность в диапазоне от 10,0 мкс до 8,1 с при возможности изменения соотношения длительности импульсов и пауз от 1:1 до 1:9.</p></abstract><trans-abstract xml:lang="en"><p>Recently, there has been a tendency in the industry to use electrochemical processing methods based on the use of milli- and microsecond pulses of different polarity and amplitude instead of a direct current. The use of a pulsed current in many cases makes it possible to obtain the desired effect by cheaper means and to provide additional controllability of the electrochemical process by adjusting the time parameters of the current pulses. This also ensures reduction of the energy costs of the polishing and cleaning process of surfaces as compared to direct current processing and increasing the efficiency of processing when the rate of smoothing the surface microroughness referred to the total removal of the metal rises significantly. For example, the application of bipolar pulses in polishing of many metallic materials eliminates the use of expensive and hazardous chromium electrolytes. The use of pulse mode during electrolyte-plasma polishing makes it possible to achieve the reduction of energy consumption and to increase of process efficiency while maintaining high intensity, processing quality and environmental safety. In order to study the effect of pulses parameters and the duration of a pause between them on the characteristics of the surface of parts made of various metallic materials in electrochemical and electrolyte-plasma processing modes the special power supply was modeled, designed and manufactured. The power supply provides the possibility of regulation frequency, the duration of the positive and negative pulses and the duration of the pauses between them a wide range. It makes it possible to generate current pulses up to 50 A at a voltage of 0 to 400 V of positive and negative polarities and is able to regulate their duration in the range from 10.0 μs to 8.1 s with the possibility of changing the ratio of the pulse duration and pauses from 1:1 to 1:9.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>источник питания</kwd><kwd>биполярное импульсное электрохимическое полирование</kwd><kwd>электролитно-плазменное полирование</kwd><kwd>частота</kwd><kwd>амплитуда</kwd></kwd-group><kwd-group xml:lang="en"><kwd>power supply</kwd><kwd>bipolar pulse electrochemical polishing</kwd><kwd>electrolyte-plasma treatment</kwd><kwd>frequency</kwd><kwd>amplitude</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Галанин, С.
