Surface compositional modifications of binary alloys during 15-keV O/sup +//sub 2/ bombardment under 45/sup 0/ incidence were studied using Auger electron spectroscopy under ultrahigh vacuum conditions. For A1-Ni, Cr-Ni, Fe-Ni, and Pd-Ni alloys, the reactive preferential sputtering by O/sup +//sub 2/ causes a surface enrichment of the alloy component which has the smaller metal-oxygen bond energy per metal atom. For Cu-Ni and Ag-Pd alloys, where oxidation by the O/sup +//sub 2/ beam was slight, the surface compositions after O/sup +//sub 2/ bombardment were qualitatively similar to those caused by nonreactive preferential sputtering with Ar/sup +/.
