Research on the Material Removal Mechanism and Experiments of Electrolytic Plasma Polishing for High-Strength Steel

This study investigates the material removal mechanism of electrolytic plasma polishing for high-strength steel through integrated multi-physics modeling and experimental validation, revealing that surface leveling is driven by electrochemical dissolution, fluid erosion, and localized discharge at asperity tips, which collectively significantly reduce surface roughness and improve surface quality.
