医用钛合金表面改性技术研究进展

Research progress of surface modification technology of biomedical titanium alloy

钛合金因其合适的弹性模量、高强度、良好的耐蚀性等特点在生物医用领域有着广泛的应用。然而钛合金耐磨性、耐疲劳性、生物相容性和抗菌性较差,对器械使用寿命、植入物的成功率等方面有很大影响,主要介绍了通过表面改性技术来提高钛合金耐磨性、耐疲劳性能、生物相容性抗菌性,并展望其未来可能的发展方向。

Titanium alloys were widely used in the biomedical field due to its suitable elastic modulus,high strength,good corrosion resistance and other characteristics.However,titanium alloys have poor wear resistance,fatigue resistance,biocompatibility,and antibacterial properties,which have a great impact on the service life of the device and the success rate of implants.Therefore,this study mainly introduces the surface modification technology to improve the wear resistance,fatigue resistance,biocompatibility and antibacterial properties of titanium alloys,and look forward to its possible future development directions.
