INVESTIGATION OF PHOSPHOROUS BULK DIFFUSION IN Ni_(84)P_(16)AMORPHOUS ALLOY BY MEANS OF AES
用表面偏析法研究磷原子在Ni_(84)P_(16)非晶合金中的扩散

The surface segregation of phosphorous in Ni_(84)P_(16)amorphous alloy has beeninvestigated by means of AES with heating in situ.Within the experimental temperatures,thesurface segregation of P was controlled by bulk diffusion,surface concentrations varie
