医用Ti6A14V合金表面改性研究进展

摘要

Ti6Al4V alloy is extensively applied in the field of the replacement and restoration for surgical implants owning to its excellent mechanical performance and good biocompatibility. However, because of the poor wear resistance, bio-activity and so on, it is really important to modify the surface of Ti6Al4V alloy. This paper introduces the effective methods to improve the properties, and summarizes the research achievement of surface modification. The development trend of surface modification is prospected.%Ti6A14V合金因具有优异的力学性能和良好的生物相容性而被广泛应用于人体硬组织替代物和修复物领域。由于合金本身耐摩擦磨损性差，不具备生物活性等缺点，因此对Ti6A14V合金进行表面改性具有重要意义。本文介绍对Ti6A14V合金进行改性的有效方法，综述了其表面改性的研究进展，展望了表面改性的发展趋势。
