This study investigates the influence of electrolytic cell parameters on electrolyte boiling rate during plasma processing, a critical stage for formation and subsequent surface modification. Focusing coaxial configuration with conical anode cylindrical cathode, this research employs analytical calculations based solution Laplace equation in spherical coordinates, validated by numerical simulations using finite element method (Elcut 6.6), to predict times. These results are compared experimental data, demonstrating good agreement, particularly at higher voltages (−200 V). The analysis reveals that while simplified model provides reasonable first approximation, it deviates lower (−50 V) due increasing importance heat removal, neglected construction. discrepancy underscores need more sophisticated models accounting non-uniform current distribution transfer effects complex geometries. findings contribute deeper understanding cathodic processing (EPP) dynamics provide foundation optimizing design process industrial applications such as diffusion saturation steel components.
