摘　　要：与其他生物医用材料相比,生物医用金属材料具有更加优异的综合力学性能和加工成型能力,并且在骨植入器件、口腔医学和心血管疾病治疗医学等领域均得到了极其广泛的应用。由于生物医用金属材料需要在体液这种复杂的生理环境下进行服役,对其性能的要求十分严格。生物医用金属材料不仅需要在力学及其相关的物理性能方面满足要求,在抗生理腐蚀性能和生物相容性方面均需要表现出优异的特性。表面改性是指在保持材料或器件原性能的前提下赋予其表面新的性能,如耐腐蚀性及生物相容性等,是进一步提高医用金属材料表面性能的重要途径。本文根据材料的特点以及应用中存在的主要问题,综述了各类医用金属材料表面改性的研究现状,并对今后新型医用金属材料的发展方向进行了展望。Because of thebetter comprehensive mechanical properties and molding capacity than other biomedical materials,biomedical metal materials have been widely used in orthopedics,dentistry,cardiovascular disease treatment and other fields.Due to the working condition in such a complex physiological environment as body fluids,the requirements of biomedical metal materials are very strict.In addition to the mechanical and related physical properties,biomedical metal materials also should have excellent resistance to physiological corrosion and bio-compatibility.Surface modification technology,which can improve the performance of implanted devices and maintain the structural stability,has been widely used in various kinds of implanted devices.Based on the characteristics of the materials and the main problems in their application,this paper summarized the research status of surface modification of various kinds of medical metal materials,and prospected the development direction of new medical metal materials in the future.
