Influence of anode immersion speed on current and power in plasma electrolytic polishing [Elektronski vir]Valentinčič, Joško ...Plasma electrolytic polishing (PeP) is mainly used to improve the surface quality and thus the performance of electrically conductive parts. It is usually used as an anodic process, i.e., the ... workpiece is positively charged. However, the process is susceptible to high current peaks during the formation of the vapour–gaseous envelope, especially when polishing workpieces with a large surface area. In this study, the influence of the anode immersion speed on the current peaks and the average power during the initialisation of the PeP process is investigated for an anode the size of a microreactor mould insert. Through systematic experimentation and analysis, this work provides insights into the control of the initialisation process by modulating the anode immersion speed. The results clarify the relationship between immersion speed, peak current, and average power and provide a novel approach to improve process efficiency in PeP. The highest peak current and average power occur when the electrolyte splashes over the top of the anode and not, as expected, when the anode touches the electrolyte. By immersion of the anode while the voltage is applied to the anode and counterelectrode, the reduction of both parameters is over 80%.Source: Micromachines [Elektronski vir]. - ISSN 2072-666X (Vol. 15, iss. 6, [article no.] 783, 2024, str. 1-13)Type of material - e-article ; adult, seriousPublish date - 2024Language - englishCOBISS.SI-ID - 199241731
