Electrolyte-Plasma Treatment in Controlled Pulse Modes

Electrolyte-plasma treatment (EPT) has become widespread in industry as an alternative to traditional chemical, electrochemical and mechanical methods of improving the surface quality products made metallic materials. The advantages EPT are a high intensity smoothing microroughnesses, use low-concentration salt solutions electrolytes, ability process items complex shape. main disadvantage method is its energy consumption; therefore, сan be classified energy-intensive production. To reduce increase efficiency materials while maintaining intensity, processing environmental safety, we proposed fundamentally new pulse (pulsed EPT), which combines both EPT. realized by combining two alternating stages within one millisecond pulse: electrolyte-plasma. developed achieved due intensive metal removal during implementation stage with current density optimization duration electrolyte-plasma stage, provides quality. A decrease repetition period pulses their makes it possible component provide more removal, remove significant irregularities. An simultaneous permits achieve low roughness general process. As result work, influence characteristics process, concentration temperature electrolyte on been investigated, comparative analysis using pulsed instead at constant voltage carried out. It found that rate than five times higher based voltage, 40 μm/min, costs for 19 % less.
