Surface chemistry can play a major role in corrosion of metals. Optimum control of this surface chemistry requires careful, detailed chemical analysis of the outer few Angstroms of the surface, using sensitive analytical instruments. Surface contamination of original Al and steel as manufactured have been investigated by Secondary Ion Mass Spectroscopy (SIMS) and Ion Scattering Spectroscopy (ISS). Fe subjected to electrochemical passivation, conversion, passivation coatings, and corrosion inhibitors has been studied also. The chemistry of these surfaces and how it affects corrosion or adhesion are discussed.
