ResumoThe surface segregation in an Ir-2%Pt alloy has been studied using Auger electron spectroscopy. The variation of the probing depth with Auger electron energy was utilized for estimating the in-depth segregation profile. After annealing at 950°C and cooling to room temperature, Auger spectra were recorded in five different kinetic energy regions. The quantitative analysis of four of these spectra was performed using computer added spectra from pure Ir and Pt. A strong segregation of Pt to the surface layer was observed.
