| Résumé : | Surface segregation of AgPd, CuPd and CuRh single crystals was studied by AES. The samples were either massive alloys or epitaxial thin films deposited on MgO. A weak surface segregation of silver was detected in AgPd alloys while the surfaces of CuPd and CuRh alloys were enriched in copper. The diffusion of copper and silver to the surface during heat treatments can be easily shown by looking at the behaviour of the Auger low-energy peaks. Our results were compared with previously published data and with theoretical models. The element with the lower surface energy segregates but not as strongly as suggested by the ideal solution model. © 1994. |
