The anode target is the anode of the X-ray tube. As the core component of the X-ray tube, its function is to receive electron bombardment to generate X-rays and release heat at the same time. Because tungsten has a high melting point, low vapor pressure, and can produce X-rays when irradiated by high-speed electron beams, it is often used as a target surface material in the anode targets of various X-ray tubes. The addition of rhenium can make the target material have the advantages of high strength, toughness, heat resistance and high precision.
1. Good ray generation rate.
2. Since the base body is made of TZM alloy, the load on the rotor bearing that supports its rotation is small, which increases the service life of the ray tube.
3. The "rhenium effect" reduces the notch sensitivity of the working surface and increases its resistance to melt loss. Rhenium has good uniformity.
4. The joint surface is firm.
5. High density.
6. Use solid-liquid mixing method to improve the uniformity of rhenium. Our company uses solid-liquid mixing method to improve the uniformity of rhenium. At the same time, we increase the density and improve the structure through multiple forging and annealing to improve the performance and life of the anode target. .
