Abstract
AbstractNickel– phosphorus alloy films, deposited on titanium by electroless NiP plating, were studied by means of total electron yield (TEY) x‐ray absorption fine structure (XAFS) and x‐ray diffraction (XRD). XAFS spectra were analyzed by the discrete variational Xα (DV‐Xα) molecular orbital method and XAFS spectral simulation using photoelectron multiple scattering theory (FEFF8), in order to clarify the deposition mechanism of Ni3P from NiP alloy films under various heating conditions. As for the electroless NiP plating, the quasi‐intermetallic compounds of Ni3P were formed under as‐deposited conditions before the heat treatment. The samples obtained after the heat treatment were in the form of larger crystal grains of Ni3P structure. Copyright © 2001 John Wiley & Sons, Ltd.
