摘　　要：激光作为一种高效、清洁热源,在材料表面改性中占有重要地位。激光表面处理可以调控材料表面组织结构和合金成分,改善材料的耐磨、耐腐蚀和抗菌等性能。钛及钛合金具有优异的力学性能、生物相容性和耐腐蚀性能,是人体硬组织的主要替代产品之一,在生物医用材料领域得到广泛应用。但钛及钛合金不具有抗菌性能,在植入过程中易发生细菌感染而造成植入手术失败,是目前钛合金骨科植入手术中亟待解决的问题。该文针对钛合金抗菌性差的问题,采用激光表面处理工艺,综述了激光表面合金化、激光表面织构和激光熔覆等激光表面改性技术改善钛合金抗菌性能的研究现状,阐明其抗菌机理,并对发展趋势进行展望,为激光技术提高钛合金抗菌性能的深入研究及应用提供理论基础及技术支撑。As an efficient and clean heat source,laser plays an important role in the surface modification of materials.Laser surface treatment can regulate surface structure and alloy composition of material,and improve wear resistance,corrosion resistance and antibacterial properties of material.Titanium and titanium alloys have excellent mechanical properties,biocompatibility and corrosion resistance.They are one of the main substitutes for human hard tissue and are widely used in the field of biomedical materials.However,titanium and titanium alloys do not have antibacterial properties,and are prone to bacterial infection during implantation,resulting in failure of implantation surgery.It is an urgent problem to be solved in titanium alloy orthopedic implantation surgery.In this paper,aiming at the problem of poor antibacterial properties of titanium alloys,laser surface treatment process is used.Research status of laser surface modification technologies such as laser surface alloying,laser surface texture and laser cladding to improve antibacterial properties of titanium alloys is reviewed.Antibacterial mechanism is clarified,and development trend is prospected,which provides theoretical basis and technical support for the in-depth study and application of laser technology to improve antibacterial properties of titanium alloys.
