The corrosion resistance of three different TiN coatings on iron(single TiN layer, Ti/TiN bilayer andTi/TiN/Ti/TiN multilayer) subjected to a salt(ammonium sulphate and sodium chloride) fog spray(Prohesion) test has been investigated by means ofx‐ray photoelectron spectroscopy (XPS). The relativeintensities of the Fe 2p and O 1s signals in the XPS spectra of thecorroded samples increase with their extent of degradation. Theresults show that the corrosion resistance of these coatings decreasein the order bilayer>multilayer>single layer. Copyright ©1999 John Wiley & Sons Ltd.
