摘　　要：目的:通过等离子浸没注入对钛合金(Ti6Al4V,下同)试样进行表面改性,分析改性后钛合金试样表面的成分。方法:利用等离子浸没注入的方法钛合金表面进行氮离子注入,用X射线衍射和X射线光电子能谱对注入层进行成分分析。结果:离子注入改性后试样的颜色呈淡金黄色色泽,X射线衍射分析和X射线光电子能谱分析结果表明改性后试样的注入层形成了含氮化钛的改性层,其主要化学成分为TiN和Ti4N2.33,不同的基体其氮化物的组成比例有一定的差别。结论:用氮等离子浸没注入的方法处理钛合金试样,能在其表面改性层生成钛的氮化物。Objective：To analyze the modified surfaces of Ti6Al4V by means of plasma ion implantation technique.Methods：Nitrogen was implanted into the surface of Ti6Al4V using plasma ion implantation.The implanted layer was analyzed by X-ray diffraction and X-ray photoelectron spectroscopy,respectively.Results：The samples modified by plasma ion implantation was light golden in color.X-ray diffraction and X-ray photoelectron spectroscopy detected TiN in the implanted layer,which was generally composed of TiN and Ti4N2.33 and the composition in different substrates varied.Conclusion：To form nitride in the implanted layer on the modified surfaces of Ti6Al4V using plasma ion implantation technique.
