Rare earth Molybdenum alloy wire material and its preparation method
In recent years, the refractory metal Tungsten and Molybdenum pipes have the advantages of high melting point, high strength, low thermal expansion coefficient, low resistivity, good thermal stability and the like, and are widely applied to the fields of sputtering coating industry, aerospace and nuclear industry. This paper starts with the application of the refractory metal Tungsten and Molybdenum pipe, and mainly analyzes the present preparation method of Tungsten and Molybdenum pipe, including the process characteristics of extrusion, forging, spinning, hot isostatic pressing, plasma spraying, chemical vapor deposition (CVD), etc., the performance advantage and application direction of the pipe, The research and development direction of the refractory metal Tungsten and Molybdenum in the future is put forward. The large-size high-purity Molybdenum and Molybdenum alloy tubular sputtering target material used in the industries of plane display, solar photovoltaic and the like is the most important high-end application development direction of the refractory metal Tungsten and Molybdenum materials, The related basic research work and equipment investment need to be further strengthened in the preparation of Mo and its alloy tube target.
