Abstract
The anodic behavior of silver was investigated under controlled diffusion conditions in alkaline solutions. Experiments were carried out under linear flow control and also using a rotating disk electrode. The electrical and optical properties of the silver oxide films were measured. On the basis of these results, we point out the difficulties involved with surface roughness in interpreting diffusion layer kinetics. Finally, we suggest a mechanism for film formation under stirred conditions, involving dissolution of silver followed by precipitation, the rate‐controlling step for which is nucleation of steps on the oxide surface.
