Abstract

In this work, we report for the first time on the use of melt spun glass-forming alloys - TiZrSi (TZS) and TiZrSiNb (TZSN) - as substrates for the growth of anodic oxide nanotube layers. Upon their anodization in ethylene glycol based electrolytes, highly ordered nanotube layers were achieved. In comparison to TiO nanotube layers grown on Ti foils, under the same conditions for reference, smaller diameter nanotubes (~~116nm for TZS and ~90nm for TZSN) and shorter nanotubes (~~11.5μm and ~6.5μm for TZS and TZSN, respectively) were obtained for both amorphous alloys. Furthermore, TEM and STEM studies, coupled with EDX analysis, revealed a double-wall structure of the as-grown amorphous oxide nanotubes with Ti species being enriched in the inner wall, and Si species in the outer wall, whereby Zr and Nb species were homogeneously distributed.

摘要

在本研究中，我们首次报道了使用熔纺玻璃形成合金——TiZrSi（TZS）和TiZrSiNb（TZSN）——作为阳极氧化纳米管层生长的基底。在基于乙二醇的电解质中对它们进行阳极氧化后，获得了高度有序的纳米管层。与在相同条件下作为参考在钛箔上生长的TiO纳米管层相比，两种非晶合金均获得了直径更小的纳米管（TZS约为116nm，TZSN约为90nm）和更短的纳米管（TZS和TZSN分别约为11.5μm和6.5μm）。此外，透射电子显微镜（TEM）和扫描透射电子显微镜（STEM）研究以及能谱分析（EDX）表明，所生长的非晶氧化物纳米管具有双壁结构，Ti物种富集在内壁，Si物种富集在外壁，而Zr和Nb物种均匀分布。
