Anodic levelling of model profiles with pulsating current

  • C. Clerc

The rate of anodic levelling with pulsating current is being investigated with triangular model profiles made of nickel using a flow channel cell. Observed results are compared to theoretical calculations of the rate of anodic levelling of macroprofiles and of microprofiles under d.c. conditions. It follows that the rate of anodic levelling is smaller above the pulse-limiting current density than that below it, and is smaller than that predicted for an ideal macroprofile. With pulsating current the rate of levelling of macroprofiles did not depend on profile orientation with respect to electrolyte flow.
