摘 要: Ti-2Al-2.5Zr合金中注入能量為75keV的N+離子，注入劑量為3×1017/cm2和8×1017/cm2，注入過程樣品的溫度低于200℃。N+離子在Ti-2Al-2.5Zr合金中的射程借助TRIM 96程序計算為1222Å。注入后的樣品用X射線衍射方法(XRD)以及光電子能譜方法(XPS)進行分析。XRD衍射譜表明有新相生成，經(jīng)分析為TiN和TiO2，但這些新相的峰非常微弱，很難區(qū)分。XPS寬程掃描譜表明注入后樣品表面主要為Ti，C，N和O。XPS關(guān)于Ti2p和N1s窄程掃描譜表明N+離子注入后在合金表面確實形成了TiN和TiO2。

Abstract:Ti-2Al-2.5Zr alloys were implanted with 75keV N+ ions at temperature lower than 200℃ with implanting dosage of 3×1017/cm2 and 8×1017/cm2. The projected range was about 1222Å calculated by TRIM 96 program. The implanted samples were analyzed using X-ray diffractometer (XRD) and X-ray photoelectron spectrometer (XPS). The X-ray diffraction patterns show that the peaks correspond to new phases， TiN and TiO2 after N+ ion implantation. But the peaks for the phases are small and difficult to distinguish. XPS surveys show there are Ti，C，N and O. High-resolution XPS collections of the Ti2p and N1s binding energy show that TiN and TiO2 are formed after N+ ion implantation.
