| 摘 要： | The surface layer of Ni_(68)P_(18)Cr_(14) amorphous alloy was studied by AES and XPS associated with ion beam sputtering. It was found that great differences existed between the surface layer and the bulk both in composition and chemical states. The dominant component elements Ni and P were of lower content in the surface laver, while Cr was enriched. Cr was drastically oxidized in the surface layer, but Ni underwent no oxidation. There was a P enriched region just helow the surface oxide layer, which was supposed to enhance the surface segregation of Cr. Ni underwent no oxidation in Ni_(68)P_(18)Cr_(14) amorphous alloy.
