Abstract
Hydrous iron oxide layers electrochemically formed on iron electrodes in different electrolytes (8.9 < pH < 12.6) have been investigated by ellipsometry. Data have been interpreted on the basis of a duplex oxid e layer structure consisting of an inner barrier layer and an outer hy drous layer. The optical response of the hydrous oxide layer depends o n the solution composition and in particular on the presence of carbon ate ions and the applied potential.
