In this study, surface phenomena of hydroxyapatite (HA) film on the nanopore formed Ti-29Nb-xZr alloy by anodization for bioimplants have been investigated by electron beam physical vapor deposition (EB-PVD), field emission scanning electron microscope (FE-SEM), X-ray diffractometer (XRD), potentiostat and contact angle. The microstructure of Ti-29Nb-xZr alloys exhibited equiaxed structure and alpha" phase decreased, whereas beta phase increased as Zr content increased. The increment of Zr contents in HA coated nanotubular Ti-29Nb-xZr alloys showed good corrosion potential in 0.9% NaCI solution. The wettability of HA coated nanotubular surface was higher than that of non-coated samples.
在本研究中，通过电子束物理气相沉积（EB-PVD）、场发射扫描电子显微镜（FE-SEM）、X射线衍射仪（XRD）、恒电位仪和接触角对通过阳极氧化在用于生物植入物的纳米孔形成的Ti-29Nb-xZr合金上的羟基磷灰石（HA）膜的表面现象进行了研究。Ti-29Nb-xZr合金的微观结构呈现等轴结构，随着Zr含量的增加，α″相减少，而β相增加。HA涂层纳米管Ti-29Nb-xZr合金中Zr含量的增加在0.9%氯化钠溶液中显示出良好的耐腐蚀性能。HA涂层纳米管表面的润湿性高于未涂层样品。
