摘要
利用铀的电子能量损失谱(EELS)、俄歇电子能谱(AES)原位,研究了在室温下O2气氛中表面Ti膜初始氧化过程中表面结构的变化。结果表明,Ti膜的氧化速度比金属Ti更快;Ti膜氧化时与金属Ti一样可形成Ti(固溶O)、TiO、Ti2O3、TiO2,氧化物以岛状形式生长,并以多种氧化态并存;其氧化过程为Ti→Ti(固溶O)→TiO→Ti2O3→TiO2。
The initial oxidation of coating Ti on uranium is in situ studied by AES and EELS in super high vacuum oxygen atmosphere at room temperature. The results show that the initial oxidation speed of Ti coating is faster than that of metal Ti. The Ti coating may form solid-solution-O Ti, TiO, Ti2O3 and TiO2 when it is oxidized in super high vacuum oxygen atmosphere. Its oxide grows in the form of island, and multi-oxidation coexists. The oxidation process of coating and metal Ti is Ti→Ti(solution O)→TiO→Ti2O3→TiO2.
