✦ Synopsis
Logarithmic growth kinetics with a rate law similar to the Elovich law account for metallic alternating‐current electrochemical impregnation of the porous part of the anodised layer on aluminum alloys 1050A and 2024T3. The relation is based on the assumption that the rate of the limiting step decreases as a function of the amount of metal already deposited, which exerts a hindering effect on the reduction of aquatized metal cations; it is valid independent of the structure of the porous layer (columnar or spongy) and the deposited metal (Ni or Zn).
