TiNbSn合金上的二氧化钛的微观结构和表面化学，通过阳极氧化在醋酸电解质和随后的热水（HW）处理制备的，已被研究，以确定HW处理对生物活性的影响。HW处理促进TiO2的形成和光诱导性能上观察到的阳极氧化。横截面能量色散谱分析植入的阳极TiNbSn与HW处理揭示了渗透的骨，钙和磷的组成元素，进入TiO 2，这是由于骨和植入的合金之间的高结合强度。有人提出，作为HW处理的结果观察到的高生物活性可以归因于结晶阳极氧化物TiO 2的演变，这促进了骨的主要成分在氧化物中的掺入。(C)2017爱思唯尔B.V.保留所有权利。
The microstructure and surface chemistry of titanium dioxide on TiNbSn alloy, prepared by anodic oxidation in acetic acid electrolytes and subsequent hot water (HW) treatment, have been studied to determine the effect of HW treatment on bioactivity. HW treatment promotes TiO2 formation and photo-induced properties were observed on the anodic oxide. Cross-section energy dispersive spectroscopy analysis of the implanted anodic TiNbSn treated with HW revealed the penetration of the constituent elements of bone, Ca and P, into TiO2, which was attributed to the high bonding strength between the bone and the implanted alloy. It is proposed that the high bioactivity observed as a result of HW treatment can be ascribed to the evolution of a crystallized anodic oxide TiO2, which promotes incorporation of the primary ingredients of a bone in the oxide.
