摘要：

Temperature dependent surface segregation studies using Auger electron spectroscopy have been performed on three different Pt-Au alloys, containing 2, 5 and 90 wt% Au. By utilizing Auger transitions of different kinetic energies and model segregation profiles, an estimate of the in-depth variation in composition was made. Strong surface segregation of Au was observed in the three alloys.
