摘　　要：目的　研究氨基基团注入纯钛表面后 ,材料表面的微观结构和化学组成。方法　在室温下将氨基以每平方厘米 5× 10 1 7,1× 10 1 7和 5× 10 1 6 离子的注入剂量注入到纯钛表面 ,注入能量为 10 0keV ,离子束电流密度为 10 μA cm2 。对改性材料进行X射线光电子能谱分析 ,以研究注入后材料表面的化学成分 ,并通过扫描电镜观察材料注入前后表面物理结构的变化。结果　得到了XPS全谱、结合能值以及扫描电镜照片 ,发现注入后 ,样品表面由氧、钛、碳、氮元素组成 ,用高斯拟合对材料表面可能存在的元素化学状态进行了分析。扫描电镜结果发现材料表面结构在注入前后未发生明显变化。结论　氨基基团注入可成功地将有机氨基基团引入到纯钛材料表面 ,形成以TiN为主的含钛、氨基化合物的改性层。Objective\ The purpose of this study was to determine the effects of amino group implantation on the surface structures of titanium.Methods\ The amino groups were implanted into the surfaces of titanium using 100 keV amino group ions at ambient temperature (25℃) with the following three different doses: 5×10\+\{17\}, 1×10\+\{17\} and 5×10\+\{16\} ions per cm\+2. The current density of the ion_beam was (10 μA/cm\+2. The modified surfaces were characterized using X_ray photoelectron spectroscopy (XPS) to determine the chemical components of the modified surfaces. A scanning electron microscope (SEM) was used to study the physical structure of the surfaces.Results\ The wide XPS profiles, the binding energy data and the SEM photos were obtained. The XPS showed that the modified surface contained Ti, O, C and N. The possible chemical states were speculated using Gauss matching analysis. There was no significant difference between the surfaces with and without implanted amino groups.Conclusion\ The XPS data reveals that the structure of the modified surface layer of aminogroup_implanted titanium is TiN, comprising a complex structure of titanium and amino compound near the surface. The SEM Photos show that this technique has little effect on the surface structures of materials.\;
