Abstract: Zinc is highly reactive in all kinds of environments and has a natural tendency to form different types of corrosion products with different corrosion rates. Electrochemical studies typically use a conventional three-electrode setup to study the mechanisms and propose advanced corrosion models. However, for certain electrochemical applications a two-electrode configuration is more suitable. In particular, the analysis of atmospheric corrosion with microelectrodes under very thin electrolyte layers would benefit from such a configuration. In this investigation, a two-electrode configuration was compared with a conventional three-electrode cell to study the corrosion behavior of zinc.
