Tungsten Rhenium Sputtering Target
Uses: Tungsten-rhenium alloy has good electrical properties, ductility and processability, and can be used for thermocouple temperature measurement in high temperature furnaces.
Applicable conditions: due to the excellent high temperature strength and high temperature plasticity of W-Re alloy, various structural parts, heaters and special-shaped parts made of W-Re alloy are widely used in aerospace, atomic energy, ultra-high temperature alloy, semiconductor magnetron sputtering, high temperature heat field and other industrial fields.
For X-ray tube, tungsten rhenium molybdenum alloy layer composite anode target material and its preparation method are used. The target material includes tungsten rhenium alloy layer and molybdenum alloy layer. The tungsten rhenium pre alloy powder is prepared by mixing tungsten powder and ammonium rhenate solution and reducing after drying. In the tungsten rhenium pre alloy powder, the mass fraction of rhenium is 1-5%, and the surplus is tungsten. The target material is made of tungsten powder, ammonium rhenate and molybdenum alloy powder by prealloying, molding, medium frequency sintering, high temperature shaping and machining. The high activity tungsten rhenium pre alloy coating powder with special proportion prepared by the invention has more uniform composition and higher activity. The tungsten rhenium molybdenum alloy layer composite anode target with uniform composition and fine and uniform grain structure is prepared by the invention. The qualified rate of the finished product is high, the process is few, and the cost is low.
Although molybdenum target X-ray tube is clear for soft tissue radiography. However, the effect on the breasts of adolescent women and the dense breasts that have not yet been breastfed is poor, especially when the thickness of soft tissue is more than 6cm, it is difficult to take pictures. For this reason, JINXING MATECH uses tungsten rhenium alloy as the target of X-ray tube.

Rhenium is a rare metal element, located at the 75th position of the periodic table of elements, adjacent to tungsten (74). Rhenium is known for its melting point of 3180 ℃, which is the second refractory metal.
In the field of alloy, tungsten and molybdenum are the most combined metal elements with rhenium. Rhenium can improve the strength and plasticity of tungsten and molybdenum at the same time, which is called "rhenium effect". Adding a small amount of 3% ~ 5% rhenium can increase the recrystallization starting temperature of tungsten by 300 ℃ ~ 500 ℃, and improve its high temperature strength and plasticity.
Rhenium alloy has a series of excellent properties, such as high melting point, high strength, high hardness, high plasticity, high recrystallization temperature, high resistivity, low vapor pressure, low electron work and low plastic brittle transition temperature.
