Plasma electrolytic polishing (PeP) is an innovative method that enables high-gloss, low-surface roughness, high polish efficiency and utilizes environmentally sustainable electrolytes. PeP has gained considerable interest in recent years owing to its ability to deliver enhanced surface quality, lower contamination levels, and broad material compatibility when compared with mechanical, chemical, and conventional electrolytic polishing methods. This method also provides an effective solution for smoothing the surfaces of components produced through additive manufacturing (AM). The surface finish and material removal behavior in PeP are influenced by multiple interacting process parameters, including voltage, current density, polishing time, electrolyte composition, concentration, and temperature. The other process parameters that require consideration include the electrode materials, interelectrode distance, the anode/cathode ratio, immersion speed and depth. Controlling these parameters is critical for gloss, surface quality, and polishing efficiency. Recent developments involving magnetic-field, ultrasonic, and jet-assisted PeP configurations have further enhanced polishing efficiency and expanded the achievable application range. Nevertheless, fundamental issues such as the formation of gas layers, the mechanisms of microdischarges, and the effects of dissolution processes on surface roughness remain under discussion. Future automation, optimization, and numerical modeling efforts are expected to make this technology more reliable and applicable on an industrial scale. This review provides a systematic overview of PeP, addressing its physical and chemical principles, its comparison to other post-processing technologies, and the conditions and outcomes of its practical applications, thereby functioning as a helpful guide for researchers.
