摘要

本研究旨在通过系统研究Zr含量对Ti-Zr- nb合金微观组织演变和腐蚀行为的影响，开发一种适用于酸性环境的耐腐蚀钛合金。结果表明，Zr的加入显著提高了合金在盐酸环境中的钝化能力和腐蚀稳定性。Ti45Zr45Nb10合金表现出优异的腐蚀性能，腐蚀电位为-153.07 mV，腐蚀电流密度为0.11 μA·cm-2，腐蚀速率仅为0.003 mm·年-1。有趣的是，在相同的腐蚀条件下，不同的样品显示出不同的干涉颜色变化。这些发现为通过优化其成分来设计具有更好耐腐蚀性的钛合金提供了有价值的见解。

Improving the corrosion resistance of Ti-Zr-Nb alloy in hydrochloric acid environment via varying Zr content

In this work, the aim is to develop a corrosion resistant Ti alloy for acidic environments by systematically investigating the influence of Zr content on the microstructure evolution and corrosion behavior of Ti-Zr-Nb alloy. The results indicate that the addition of Zr significantly enhances the passivation ability and corrosion stability of the alloy in hydrochloric acid environments. The Ti₄₅Zr₄₅Nb₁₀ alloy exhibits superior performance with a corrosion potential of -153.07 mV, corrosion current density of 0.11 μA·cm^-2 and corrosion rate of only 0.003 mm·year^-1. Interestingly, under identical corrosion conditions, different specimens displayed distinct interference color variations. These findings offer valuable insights for the design of Ti alloys with improved corrosion resistance, achieved through the optimization of their composition.
