Abstract
Throwing power measurements for anodic dissolution of nickel under electrochemical machining conditions were performed in a flow channel apparatus. Acidified and neutral solutions were chosen as examples of a nonpassivating and a passiyating electrolyte. Anode and cathode potential measurements and current efficiency determinations were used for the interpretation of measured throwing power data. Current distribution at high current densities was little affected by passivation. The lower throwing power found for the passivating electrolyte compared to the nonpassivating electrolyte was therefore solely due to a different dependency of dissolution efficiency on current density.
