摘要：

Combined with electron microbeam techniques such as scanning electron microscopy and electron-induced X-ray emission, a helium microbeam is used to study the effect of Ar+ ion bombardment on the surface of a binary alloy Ag37CuB63 by particle-induced X-ray emission and Rutherford backscattering. A pronounced change of the surface concentration and depth profile has been found at both Cu-enriched solid solution micro-region and Ag-enriched eutectic mixture micro-region on the alloy surface due to ion bombardment, The preferential sputtering of Ag and bombardment-induced surface segregation is suggested to be attributed to the composition change in the near-surface regions, A superposition of depth distributions determined from different micro-phase-regions is experimentally confirmed.
