Abstract

Iron, chromium and aluminum particles sputtered under 5 keV by Kr+ ion bombardment at normal incidence from the ternary alloy Fe82Cr6Al12 was simulated. The Stopping and Range of Ions in Matter (SRIM) software combined to a new code-program, called Angulaire, were used to obtain the sputtering yields and angular distributions of the ejected species. The simulation was performed for a large number of incident ions (about 2 × 105 ions) and the number of particles emitted in the solid angle corresponding to the probe was counted by a computer. The angular distributions of sputtered particles were compared with the results available in the literature and showed a reasonable agreement. Furthermore, we have demonstrated that the angular distribution of the differential sputtering yields of all ejected species (iron, aluminum, and chromium) from the ternary alloy exhibited an over-cosine tendency. © 2019 Polish Academy of Sciences.
