A new titanium alloy (Ti-12.5Zr-3Nb-2.5Sn) was developed to meet the needs of clinical requirements for medical titanium alloys and improve the properties of existing titanium alloys. The as-prepared alloy was solution treated at 500 °C for 3 h in vacuum followed by water quenching. Tensile, wear and hardness tests were carried out to examine the mechanical properties of the Ti-Zr-Nb-Sn alloy. Oral mucous membrane irritation test was performed to evaluate the surface biological properties of the Ti-Zr-Nb-Sn alloy. The results suggested that the surface hardness and wear-resistant properties of the Ti-12.5Zr-3Nb-2.5Sn alloy were superior to commercially pure Ti. The oral mucous irritation test showed that all samples had no mucous membrane irritation. It indicates that Ti-12.5Zr-3Nb-2.5Sn has large potential to be used as dental restoration material.
开发了一种新型钛合金(Ti-12.5Zr-3Nb-2.5Sn),以满足临床对医用钛合金的需求,并改善现有钛合金的性能。所制备的合金在真空度为 500°C 的条件下进行 3 小时固溶处理,然后进行水淬。通过拉伸、磨损和硬度试验来检验 Ti-Zr-Nb-Sn 合金的力学性能。通过口腔黏膜刺激试验来评价 Ti-Zr-Nb-Sn 合金的表面生物性能。结果表明,Ti-12.5Zr-3Nb-2.5Sn 合金的表面硬度和耐磨性优于工业纯钛。口腔黏膜刺激试验表明,所有样品均无黏膜刺激。这表明 Ti-12.5Zr-3Nb-2.5Sn 具有作为牙科修复材料的巨大潜力。
