摘　　要：超晶格涂层刀具因其独特的二维物相结构,具有超高的硬度及耐磨性等力学性能,广泛应用于高速切削和干切削的机械加工。试验表明,通过多弧离子镀膜技术,在原有TiN和CrN涂层制备基础上,加上适量的AL和Si元素,可以获得具有超晶格结构的复合刀具涂层,具有更高的硬度、更低的摩擦因数及良好的抗高温氧化性能和切削寿命。Because of its unique two-dimensional phase structure,the superlattice coating makes tools widely used in highspeed cutting and dry-cutting machining with its mechanical properties of high hardness and wear resistance.The results from experiments show that the composite tool coating with superlattice structure can be prepared by multi-arc ion plating technology of adding Al and Si elements on the basis of the original TiN and CrN coating preparation,with higher hardness,lower friction factor,good resistance to high temperature and oxidation,and long cutting life.
