Abstract

The purpose of this study was to investigate the control of nanotube morphology using various factors for dental implant. TiO2 nanotube formation on biomedical grade α+β type Ti-6Al-4V alloy was investigated using anodization technique as a function of applied DC potential (10 V to 30 V and 30 V to 10 V) and anodization time for 60 min in 1 M H3PO4 with small additions of NaF (0.5 wt.%, and 0.8 wt.%). The microstructure and phase characteristics of surface were examined by optical microscopy, field emission scanning electron microscopy and X-ray diffraction. Also, in order to observe the biocompatibility and surface roughness, wettability and atomic force microscopy of alloy was measured.

摘要

本研究的目的是探讨利用各种因素控制用于牙科植入物的纳米管形态。采用阳极氧化技术，研究了生物医学级α+β型Ti-6Al-4V合金上TiO2纳米管的形成情况，该过程是施加直流电势（10 V至30 V和30 V至10 V）以及在添加少量NaF（0.5 wt.%和0.8 wt.%）的1 M H3PO4中进行60分钟阳极氧化时间的函数。通过光学显微镜、场发射扫描电子显微镜和X射线衍射对表面的微观结构和相特征进行了检查。此外，为了观察合金的生物相容性以及表面粗糙度、润湿性和原子力显微镜情况进行了测量。
