钛合金具有良好的生物相容性,同时相比传统植入物金属材料有较低的弹性模量,在生物环境下具有良好的抗腐蚀性能,这些优异的性能使钛合金作为医用植入物材料备受青睐。钛及钛合金作为医用植入物材料在临床中得到广泛应用。在不同的临床应用过程中,植入物材料常因金属的降解、与骨的生长融合、抗菌等因素,而对材料本身的性能有着不同的要求。因此,制备具有优异综合性能的钛合金材料以满足临床需求是科研工作者当前面临的重要问题。本文系统介绍了医用钛合金材料的结构、性能特点及目前在骨科应用方向的研究现状,在未来研究中,将通过改变元素组成、增加表面改性、优化生产工艺等方式,使钛合金材料能够以优异的综合性能更好地服务于人类。 |

Owing to the excellent biocompatibility and corrosion resistance of titanium and its alloys in the biological environments,they are one of the best materials in the medical implant applications. Moreover,it has a lower elastic modulus (comparable to bone)than traditional metal implant materials which is an influential property due to the stress-shielding effect.There are some requirements for implant materials according to their clinical use and the periphery tissues.Hence, some factors should be considered,such as metal degradation,toxicity issues,surface characteristics, biocompatibility,and fusion with bone.Considering the above-mentioned information,titanium material design with superior performance to meet the essential clinical needs is an important challenge and attracts much attention from the academicians in the biomaterial field.This paper discusses the structural and performance characteristics of medical titanium alloys and the current research status in the direction of orthopedic applications.Furthermore,in future research,through changing the elemental composition,increasing the surface modification,and optimizing the production process, titanium alloy materials could have the excellent comprehensive performance to serve human beings better. |
