The surface segregation of antimony in an iron–0.23 at% antimony alloy was studied by XPS. The segregation rate in the temperature range between 800 and 900 K depends on the temperature during sputtering with argon ion of kinetic energy of 1 keV. The sputtering at room temperature or 473 K gives higher values of the segregation rate than those at 673 K. Both cases give the activation energy of 170 kJmol −1 for the surface segregation rate. The segregation of antimony is not observed after the sample is heated at 1000 K.
