摘　　要：利用离子辅助增强磁控溅射与蒸发镀二元组合源设备在TiCN基陶瓷刀具表面制备TiAlN涂层;为提高膜基结合力,采用蒸发镀技术预先沉积一层CrN/Cr过渡层。利用X射线衍射仪、维氏显微硬度计、洛式硬度计、摩擦磨损试验仪等设备,系统分析了CrN/Cr过渡层对涂层微观结构、显微硬度、膜基结合力及耐磨损性能的影响。结果表明,CrN/Cr过渡层的存在,使膜基结合力和涂层耐磨损性能得到大幅度提高。TiAlN coatings were deposited on the surface of TiCN ceramic tools by ion enhanced magnetron sputtering and evaporating deposition combination source equipments.In order to improve the adhesion of the TiAlN coatings to the substrate,a layer of CrN/Cr film was deposited firstly on TiCN ceramic tools by evaporating deposition.The effects were systematically investigated of CrN/Cr interlayer on microstructure,microhardness,film-substrate adhesion and wear resistance of the coatings by the equipments of X-ray diffractometer,Vickers microhardness tester,Rockwell hardness tester,friction and wear tester and so on.The results show that the CrN/Cr interlayer can effectively improve the adhesion and wear resistance of the coatings.
