The purpose of this study was to investigate surface characteristics of nanotube formed Ti–25Nb–xZr alloys. Ti–25Nb–xZr ternary alloys with 0–15 wt% Zr were manufactured in a vacuum arcmelting furnace. Ingots of the alloys were homogenized in an Ar atmosphere at 1000 °C for 12 h, followed by quenching in ice water. Nanotube layers were formed by an electrochemical method in 1 M H₃PO₄ and 0.8 wt% NaF at 30 V for 1 h. As the Zr content of the Ti–25Nb–xZr Alloys increased, the crystals transformed from a needle-like to equiaxed structure. Two nanotube sizes were obtained on the Ti–25Nb–xZr alloys. As the Zr content was increased, the diameters of the larger tubes decreased, whereas those of the smaller tubes increased. However, increased Zr content in the Ti–25Nb–xZr alloys had little effect on wettability.
本研究的目的是研究形成纳米管的Ti–25Nb–xZr合金的表面特性。在真空电弧熔炼炉中制备了Zr含量为0–15 wt%的Ti–25Nb–xZr三元合金。合金铸锭在氩气气氛中于1000 °C均匀化12小时，随后在冰水中淬火。通过电化学方法在1 M H₃PO₄和0.8 wt% NaF中于30 V下处理1小时形成纳米管层。随着Ti–25Nb–xZr合金中Zr含量的增加，晶体从针状结构转变为等轴结构。在Ti–25Nb–xZr合金上获得了两种纳米管尺寸。随着Zr含量的增加，较大纳米管的直径减小，而较小纳米管的直径增大。然而，Ti–25Nb–xZr合金中Zr含量的增加对润湿性影响不大。
