摘　　要：目的:探讨新型医用钛合金Ti-24Nb-4Zr-7.9Sn(TNZS)表面应用阳极氧化(Anodic oxidation,AD)技术进行改性的结果。方法:应用阳极氧化技术在TNZS钛合金片表面制备氧化膜层,用扫描电镜(SEM)观察其表面形貌,能谱分析仪(EDS)及X射线衍射仪(XRD)分析其元素成分和晶相结构,用接触角测量仪分析表面能。结果:电镜观察表明TNZS钛合金阳极氧化膜是由大小不等的微孔组成,直径约0.1～5μm。能谱分析证实阳极氧化膜由Ti、Nb、Zr、Sn、O、Ca元素构成。X射线衍射表明阳极氧化膜由锐钛矿型和金红石型二氧化钛组成,并且阳极氧化技术提高了TNZS钛合金的表面能。结论:阳极氧化技术可以改善TNZS钛合金的表面性能,提示可能有利于细胞的贴附生长。Objective： To evaluate the method and efficacy for Ti -24Nb -4Zr-7.6Sn （TNZS） modification by using anodic oxidation technology. Methods： TNZS alloy discs were treated with anodic oxidation. The surface morphology was observed with SEM. The element distribution and composition of oxidation film were analyzed with energy dispersive spectrum （EDS） and X -ray diffraction （XRD）. The surface energy of oxidation film was analyzed with contact angle measuring instrument. Results： The film was consisted of many microporous about 0.1 to 5μm in diameter. The oxidation film was composed of Ti, Nb, Zr, Sn, O, Ca elements. XRD indicated that the phases in the oxidation film were anatase and rutile TiO2. The surface energy of TNZS was increased after being anodic oxidation. Conclusion： The surface performance of TNZS was improved by anodic oxidation, which meant that anodic oxidation may be advantageous to the adhesion and growth of cells.
