“…Most existing models for ECM assume constant electrolyte conductivity [4][5][6][7]. In more refined models the influence of the temperature and the gas fraction on the electrolyte conductivity is accounted for [8,9].…”

A new two-dimensional model is presented that allows describing the high speed electrochemical machining of steel in NaNO 3 solutions. Unlike existing models, local ion concentrations are calculated and used to evaluate local diffusion coefficients and electrolyte conductivity. Secondly, the presence of a super-saturated, honey-like layer on the anode surface is accounted for by introducing a water depletion factor. This factor describes the suppression of the oxygen evolution as the vast increase in ion concentrations reduces the amount of free water molecules at the anode. It is demonstrated that this approach enables to reproduce experimental average efficiency curves over a broad range of electrolyte concentrations with just a limited set of adjustable parameters.

“…Ion and electrons crossing phase boundaries (the interface between two or more separate phases, such as liquid-solid) would result in electron transfer reaction carried out at both anode and cathode. Meanwhile, the potential difference is fundamental in understanding the energy distribution during the electrochemical machining process [17]. Nernst equation is used to calculate the electrode reversible potential.…”

“…The inverse problem of electrochemical shaping with the aid of a shaped tool was considered in many works [21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38], which is connected with extensive practical use of this scheme and the importance of the perfection of calculation methods for designing costly tools of intricate shapes. The ECM of sculptured surfaces by an unshaped tool started to be developed only in the last few years, in particular, when performing electrochemical micromachining (ECMM).…”
