钼钨复合旋转靶制备方法浅析OA

Molybdenum tungsten composite rotating targets can be stimulated X-rays which are suitable for X-ray examination in industri-al,healthcare,security and so on.The molybdenum tungsten composite rotating target needs to withstand a high temperature of 1 300℃during operating,especially the focal spot temperature may be over 2 300℃.In order to bear such high temperature the molybdenum tungsten composite rotating target is generally designed as a double-layer or multi-layer structure.Multi-layer structures have their own characteristics in forming,processing,and other aspects.Currently,the main preparation methods include powder metallurgy,tungsten plate molybdenum powder hot pressing composite method and vapor deposition method This article provides an in-depth analysis and discussion on the preparation methods,advantages,and disadvantages of different methods for molybdenum tungsten composite rotating targets for reference.
