The combined use of XPS and STM for the study of passive films is illustrated by the examples of a pure metal, nickel, and an alloy, Fe-22Cr. This combined approach applied to well-defined single crystal surfaces is expected to provide key information to the understanding and prediction of the stability and breakdown of thin anodic oxide layers.

AR-XPS has been extensively used to investigate the chemical composition, the chemical states and the thickness of thin anodic oxide overlayers (passive films) formed on well-defined metal and alloy single crystal surfaces. More recently direct imaging of the surface structure by STM with atomic resolution provided new data on the crystallinity, the epitaxy and the nature of the structural defects existing in the thin oxide layers. Such data are useful... [Pg.243]
