The effect of sputtering on the surface composition of an Al-Pd-Mn quasicrystal

In this paper, the effect of sputtering on the surface composition of an Al-Pd-Mn quasicrystal has been studied using 2KeV He +. It was found that the surface concentration of A1 decreases smoothly to a steady state under bombardment and the Mn and Pd concentrations increase. The surface enriched in Mn was annealed and it was found that there was no detectable surface Mn at temperatures higher than 575K. Finaly, the variation of the ratio of the Al/Pd surface concentration with changes in temperature was measured.
