✦ Synopsis

The rate of anodic levelling of macroprofiles under mass-transport control is studied analytically and by the finite element method (FEM) using the Nernst diffusion-layer approach. It is found that the rate of anodic levelling of macroprofiles is always slower than that of microprofiles and depends on the geometrical parameters eO, 6, I representing, respectively, the profile height, the diffusion-layer thickness and the profile wavelength. On sinusoidal profiles when so/S + co, the rate of levelling tends towards zero.
