We have studied the anodic behavior of Pt, Mo, Ni, and stainless steel (SS) electodes in 1.5M LiAlCl/sub 4//SOCl/sub 2/ solution in order to determine the mechanisms by which these metals resist corrosion. Polarization and complex impedance indicate that Pt and Mo behave as inert electrodes, while Ni and SS form passive films in this electrolyte. X-ray Photoelectron Spectroscopy (XPS) confirms the lack of oxidized metal species on the Pt and Mo surfaces following anodic polarization. XPS results also show that the Ni and SS do form passive layers, and identifies these layers as predominantly metal chlorides.
