利用同步辐射光电子能谱原位研究了经氧离子溅射后SUS304 不锈钢和纯金属铁、镍、铬表面氧的化学状态。氧离子溅射后，SUS304 不锈钢表面的氧全部以化合态形式存在；而在纯铁、镍、铬金属表面，只有部分氧与金属元素化合，另一部分氧以原子的形式镶嵌在金属晶格中。纯金属元素与氧的化学反应活性决定了金属中化合氧和溶解氧的比率。
The implantation behavior of O+ in SUS304 satinless steel,pure Fe,Ni and Cr has been studied by SR-XPS in situ.All of O+ ion has combined with the metal atoms in SUS304, on the other hand, only oart of O+ ion reacted with metal atoms in pure Fe, Ni and Cr.Oxygen existed in two chemical states in pure Fe,Ni,Cr: "reacted oxygen" which combined with metal element and "dissolved oxygen"which just insert into the crystal lattice.The ratio of "dissolved oxygen"is decided by the chemical reactivity the oure metal has.
