If kp ! 0, itip ! i (see the Eq. 13)) and if kp ! 1, itip ! i0 ( fc – fa) >> i. The electrochemical process on the tip of a sharp needle-like protrusion can be under pure activation control outside the diffusion layer of the macroelectrode. Inside it, the process on the tip of a protrusion is under mixed control, regardless it is under complete diffusion control on the flat part of the electrode for kp ! 0 (see section “Model of the spherical diffusion around the tip of a surface protrusion–deposition to the point”).
6f that thickening of such a protrusion is under mixed activation–diffusion control because the deposit is seen to be of the same quality as that on the surrounding macroelectrode surface. It can be seen from the Fig. 6d that activation control takes place only at the very tip of the protrusion. The Position of New Nuclei It is seen from Fig. 6c, d that new nuclei are mainly formed at the bottom of the already growing protrusions or between them. If the diffusion zones of two or more hemispherical protrusions partially overlap, as illustrated by Fig.
Let us consider the model of surface irregularities shown in Fig. 1. The electrode surface irregularities are buried deep in the diffusion layer, which is characterized by a steady linear diffusion to the flat portion of the surface [1, 6, 7], and the limiting diffusion current density is given by Eq. 14). Fig. 1 Model of a paraboloidal surface protrusion; hp is the height of the protrusion relative to the flat portion of the surface, hs is the corresponding local side elongation, r is the radius of the protrusion tip, Rb is the radius of the protrusion base, and δ is the thickness of the diffusion layer and δ >> hp (Reprinted from Refs.
