Abstract

Spatially resolved electron energy loss spectroscopy (EELS) has been used to investigate the oxidation state of tungsten species in a barrier anodic oxide film formed on an Al-6·5 at.-%W alloy in 0·1M sodium tungstate electrolyte at 293 K. Tungsten 4f core level excitation indicates the presence mainly of W⁶⁺ species in the anodic film. Insight into the bonding arrangements within the anodic oxide is also provided by valence band excitation and revelation of the oxygen edge and its associated pre-edge structure.
