Electrochemical Deburring (ECD) utilizes localized anodic dissolution governed by Faraday's law of electrolysis to dissolve metal burrs in seconds without mechanical contact or tool wear.
Faradaic Current Density & Dissolution Rate
Ohm's law and Faraday's law determine the dissolution current density J and linear removal rate v_diss:
J = kappa * (V - Delta_V_over) / gv_diss = eta * C_spec * Jt_cycle = h_burr / v_diss
Maintaining electrolyte flushing velocity (> 10 m/s) prevents hydrogen gas accumulation and localized thermal boiling in the micro-gap.
