本研究采用机械合金化和放电等离子烧结的方法制备了Ti-13Nb-13Zr合金，作为一种潜在的植入体生物材料。系统地研究了这些材料的相组成、显微组织、力学性能和腐蚀行为。实验结果表明，低温烧结可制备出致密细晶的全密度Ti-13Nb-13Zr合金。烧结合金主要由13个相组成，α相和α‘相均匀弥散分布，其抗压强度为1790 MPa，维氏硬度为356.7+/-3.6HV10。在Ringer‘s溶液中测试了动电位极化曲线和电化学阻抗谱，结果表明所制备的材料具有良好的耐蚀性能。
In the present study, Ti-13Nb-13Zr alloys were produced by mechanical alloying and spark plasma sintering as a potential biomaterials for implant applications. The phase composition, microstructure, mechanical properties and corrosion behavior of these materials were systematically investigated. Experimental results reveal that the fully density Ti-13Nb-13Zr alloy with fine grain can be prepared by sintering at a low temperature. The sintered alloys were mainly composed of 13 phases with alpha and alpha '' uniform dispersed, which show a compression strength of 1790MPa, as well as a Vickers hardness of 356.7 +/- 3.6 HV10. Potentiodynamic polarization curves and electrochemical impedance spectroscopy were measured in Ringer's solution, revealing the prepared materials have good corrosion resistance properties.
