摘要
通过粉末冶金技术,采用真空高温热压烧结工艺,制备了W/Mo/石墨复合靶材,并对其显微组织、结合状态、密度和硬度等性能进行了测试,结果表明在1700℃,保温4h,采用Zr,Ni,Ti混合粉作为粘结剂,热压条件下制备的W/Mo/石墨复合靶材,组织致密均匀,W,Mo层过渡平缓,结合界面良好,结合强度高。Mo层的硬度达到Hv250左右。
Tungsten/Molybdenum/Graphite composite target was prepared by utilizing powder metallurgy technology, along with vacuum hot pressing sintering technique. The microstructure, bonding state, density and hardness of the composite were analyzed. The resuits show that utilizing the mixture of Zr, Ni and Ti as adhesives, the composite target sintered at 1700 ℃, holding for 4 h under hot pressing condition had fine and dense microstructure, a gentle transition layer between tungsten and molybdenum, an excellent bonding interface and large bonding strength. The hardness of molybdenum layer could reach approximately HV250.
