| 摘 要： | 采用独立靶材在YG6硬质合金上以电弧离子镀工艺制备了TiAlN涂层,研究了钛靶弧流对涂层的微观形貌、成分和性能的影响,对TiAlN涂层的膜基结合强度及高温抗氧化性能进行了测试分析,并将TiAlN涂层的YG6硬质合金刀具与未涂层的YG6硬质合金刀具对T12工模具钢(50HRC)进行对比切削试验。结果表明:钛靶弧流为60～70A时,涂层具有较理想的表面结构,膜基结合力较好,可达44N;钛靶电流对涂层中N含量的影响不大,对Al及Ti含量有较明显的影响。在干式切削条件下,TiAlN涂层刀具的使用寿命是未涂层刀具的3倍。

| Abstract: | TiAlN coatings were deposited by multi-arc ion plating with independent targets on YG6 carbide,the influences of arc current of titanium target on microstructure and composition were researched,the bonding strength and membrane-based high temperature oxidation resistance was tested and analyzed.In addition,between the coating tools and non-coated tools cutting tests were carried out in T12 die steel.The results show that when arc current of titanium target is 60～70A,the coatings have a better surface texture and the best membrane-based adhesion with 44N. Arc current of titanium target has little influence on the content of N element,the influence of Al and Ti content is obvious. In dry cutting conditions,the service life of TiAIN coating tools is 3 times longer than that of non-coated ones. |
