The microstructure, mechanical properties and corrosion resistance of Zr-30%Ta and Zr-25%Ta-5%Ti alloy prepared by spark plasma sintering (SPS) technology were investigated. The experimental results showed that the Zr-Ta-Ti alloys made by the SPS processing have a low level of porosity with the relative density of 96%–98%. The analyses of XRD and TEM revealed that the Zr-30Ta alloy consists of α+β phase, and the Zr-25Ta-5Ti alloy belongs to the near β type alloy containing a small amount of α and ω phases. With the addition of Ti, the elastic modulus of the alloys was decreased from (99.5±7.2) GPa for Zr-30Ta alloy to (73.6±6.3) GPa for Zr-25Ta-5Ti alloy. Furthermore, it is shown that, in comparison to CP-Ti and Ti-6Al-4V alloy, the Zr-Ta-Ti alloy produced in this work offers an improved corrosion resistance due to the more stable ZrO₂ and Ta₂O₅ generated in the passivation film on the surface of the alloys. This study demonstrates that Zr-Ta-Ti alloys are a promising candidate of novel metallic biomaterials.

研究了通过火花等离子体烧结（SPS）技术制备的Zr-30％Ta和Zr-25％Ta-5％Ti合金的组织，力学性能和耐蚀性。实验结果表明，通过SPS加工制成的Zr-Ta-Ti合金的孔隙率较低，相对密度为96％–98％。XRD和TEM分析表明，Zr-30Ta合金由α+β相组成，Zr-25Ta-5Ti合金属于含有少量α和ω的近β型合金。阶段。随着Ti的添加，合金的弹性模量从Zr-30Ta合金的（99.5±7.2）GPa降低到Zr-25Ta-5Ti合金的（73.6±6.3）GPa。此外，示出的是，相比于CP-Ti系和Ti-6Al-4V合金，在这项工作报价产生的改进的耐腐蚀性的Zr-TA-Ti合金由于更稳定的ZrO ₂和Ta ₂ ö ₅产生在合金表面的钝化膜中。这项研究表明Zr-Ta-Ti合金是新型金属生物材料的有希望的候选者。
