The experimental modelling of macro-distribution of etching rates (in normal direction and in the area of undercutting) has been conducted by using anodic dissolution of macroscopically non-uniform rotating disk electrode from aluminium alloy D1 (Ag – Cu – Mn) partially insulated by thick self-sticky polyvinylchloride mask in NaCl solution (150 g/L) under direct current, pulse unipolar and bipolar (anodiccathodic machining) current as an example. We demonstrate that under conditions, when ion-transfer rate controls dissolution rate (at high current densities iavg > icr), macro-distribution cardinally changes. In this case we observe significant non-uniformity of macro-dissolution, which exceeds non-uniformity of primary current distribution on a uniform disk electrode.
