The photoresponse ofpassivatingfilms grown on tin in slightly alkalinesolutions has beenstudied under both galvanostatic and potentiostatic conditions. The response of films growing under galvanostatic conditions was used to determine the nature and magnitude of their deviation from stoichiometry, a

Copper forms passivating layers in alkaline solutions. Depending on the electrode potential a Cu,O or a Cu20/Cu0, layer is present. The structure and composition of the film has been examined by different methods like X-ray Photoelectron Spectroscopy ( X P S ) , Ion Scattering Spectroscopy (ISS) and

## Abstract The electrochemical behaviour of a Cd anode was investigated in 0.05โ2 M NaOH solutions by the potentiodynamic technique. The polarization curves exhibit active to passive transition prior to oxygen evolution. The threshold potential of the active dissolution is very close to the revers
