摘　　要：钛合金与常用类金属相比,具有更好的强度、韧性、延展性以及较好的抗氧化性与耐腐蚀性。因此这使得钛合金在航空航天、汽车技术以及医疗技术等领域中得到了广泛的应用。实现钛合金的高速、高效切削加工,切削刀具是关键。刀具涂层技术使得刀具在提高使用寿命、切削效率和加工表面质量等方面发挥着重要作用,可以很好的满足钛合金加工的需求;随着涂层技术的进步,刀具涂层朝着组成元素多元化和微观结构复合化方向发展,促进了现代工业的发展。Titanium alloy has high strength quality ratio,better strength,toughness,and malleability. In addition,titanium alloy also has good oxidation resistance and corrosion resistance,and at high temperature it can maintain good strength. These advantages make the titanium alloy widely used in aerospace,automotive,chemical and medical devices. It is the key to realize high speed and efficient machining of titanium alloy. In cutting tools coatings technology have more and more widely application,the performance of the surface of the coatings can significantly improve the cutting tools performance,with the progress of coating technology,the development of tool coating in the direction of diversification,compound and nanoization has greatly promoted the development of modern industry.
