Effect of temperature during ion sputtering on the surface segregation rate of antimony in an iron–antimony alloy at higher temperatures

Abstract

<jats:title>Abstract</jats:title><jats:p>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<jats:sup>−1</jats:sup> for the surface segregation rate. The segregation of antimony is not observed after the sample is heated at 1000 K.</jats:p>
