Notes:
The ion-beam mixing of SiC-coated Fe, Cr, Ni, Cu, and stainless steel was investigated, by means of Auger electron spectroscopy, to determine the role of thermodynamics in the process. Both inert (Ar+) and reactive (N+) ions were used at either 30 keV or 160 keV incident energy. A mechanism involving thermally activated motion of bombardment-induced defects appeared relevant to the onset of a chemical bias in the mixing. Further, the formalism established for describing ion mixing, based on Darken's analysis of chemical interdiffusion coefficients, provided a quantitative interpretation of the results.
