摘　　要：钛及钛合金具有比强度高、耐腐蚀、耐高温以及生物相容性好等优点,广泛应用于航空航天、国防军工、海洋船舶、生物医疗等重要领域。同时钛及钛合金极容易被氧化,存在硬度低、导热性差、电极电位较正等缺点,明显限制了其应用。表面处理可以改变基体的表面状态,提升视觉观感及使用性能,甚至可以获得基体不具备的某些新功能,对提高钛及钛合金产品的寿命、可靠性及扩展其应用领域具有重要意义。当前几乎所有表面处理技术都逐步延伸到钛及钛合金表面处理领域,但仍不能完全满足其使用性能要求。综述了钛及钛合金在表面修饰、表面耐磨耐腐蚀、表面着色及表面隔离4个功能领域中常用的表面处理技术的特点及研究进展,并展望了钛及钛合金表面处理技术的发展方向。Titanium and titanium alloys have many advantages such as high specific strength,corrosion resistance,high temperature resistance and excellent biocompatibility,and are widely used in aerospace,national defense and military industry,marine ships,biomedical and other important fields.At the same time,they also have some disadvantages such as oxidation-prone,low hardness,poor thermal conductivity and high electrode potential,which limit their application obviously.Surface treatment can change the surface state of substrate,improve the visual perception and performance,and even obtain some new functions that the substrate does not have,which is of great significance to improve the service life and reliability and expand the application field of titanium products.At present,almost all surface treatment technologies have been applied to the field of titanium and titanium alloys surface treatment,but still can not fully meet the performance requirements.In this paper,the characteristics and research progress of surface treatment technologies of titanium that commonly used in four functional fields are reviewed,including surface modification,surface wear and corrosion resistance,surface coloring and surface isolation,and the development direction of titanium surface treatment technology is prospected.
