Abstract In this work, the microstructural, hardness, and corrosion response of a series of Ti-30Zr alloys with Ta additions (0-5 at.%) were studied. The microstructural analysis performed by XRD and FE-SEM-EDS allowed confirmed the β-Ti and β-Zr stabilization for lower additions of Ta, while a martensitic transformation was detected for higher additions. Electrochemical and microhardness experiments showed that the Ti-30Zr-xTa alloys exhibited better corrosion resistance and microhardness enhancement compared to the Ti-30Zr alloy, especially for the sample with 3 at.% Ta addition.

用于生物医学应用的电弧熔化处理的添加 Ta 的 Ti-30Zr 合金的显微组织和腐蚀表征

摘要 在这项工作中，研究了一系列添加了 Ta (0-5 at.%) 的 Ti-30Zr 合金的显微组织、硬度和腐蚀响应。通过 XRD 和 FE-SEM-EDS 进行的显微结构分析证实了较低添加量的 β-Ti 和 β-Zr 稳定化，而较高添加量时检测到马氏体转变。电化学和显微硬度实验表明，与 Ti-30Zr 合金相比，Ti-30Zr-xTa 合金表现出更好的耐腐蚀性和显微硬度增强，特别是对于添加 3 at.% Ta 的样品。
