Abstract

The purpose of this study was to investigate the surface observation of PEO-treated Ti-6Al-4V alloy after 2-step nano-mesh formation was investigated by FE-SEM, EDS, and XRD. Anodic oxidation treatment was performed on the electrolyte containing 0.8 wt.% Na/F and 1M H₃PO₄ to form a nanotube structure on the Ti-6Al-4V alloy. After removing the nanotube layer, PEO-treatment was performed on the electrolyte containing Mg and Zn ions. After forming the nanotubes, the nanomesh surface was obtained by removing the layer, and the surface roughness increased with cycle number of nanotube formation. Also, as the number of nanotubes increased, the anatase peak increased.

摘要

本研究旨在通过 FE-SEM、EDS 和 XRD 研究两步纳米网形成后 PEO 处理 Ti-6Al-4V 合金的表面观察。在含有 0.8wt.% Na/F 和 1M H₃PO₄ 的电解液中进行阳极氧化处理，在 Ti-6Al-4V 合金上形成纳米管结构。去除纳米管层后，在含有 Mg 和 Zn 离子的电解液中进行 PEO 处理。形成纳米管后，通过去除层获得纳米网表面，表面粗糙度随纳米管形成的循环数增加而增加。而且，随着纳米管数量的增加，锐钛矿峰增加。
