Abstract

The Anodic Behavior of Iron in Anhydrous Dimethoxyethane and Passivation by Solvent Electropolymerization.-The corrosion and passivation behavior of pure iron in an anhydrous solution of 0.5 M LiAsF6 in DME is studied by various electrochemical and surface analytical techniques. It is found that iron has a stable passive region over a large range of anodic potentials in this solution. Several passivation mechanisms are identified, including the passivation caused by electropolymerization of DME. The polymerization reaction is not observed when electrolytes other than LiAsF6 are used. An oxide-free, bare metal surface appears to be necessary for the initiation of the electropolymerization reaction. -(SCANLON, J. F.; KRUGER, J.; MORAN, P. J.; J.
