Title:
FABRICATION PROCESS FOR SINGLE-CRYSTALLIZATION ANTI-EVAPORATION X-RAY TUBE ANODE TARGET
Document Type and Number:
WIPO Patent Application WO/2022/120961
Kind Code:
A1
Abstract:
A fabrication process for a single-crystallization anti-evaporation X-ray tube anode target (1), comprises the following steps: step 1, preparing a single-crystallization fabrication device and an anode target (1), wherein the anode target (1) has an anode target surface (11) annularly arranged along the circumferential direction thereof, and the single-crystallization fabrication device is provided with a working cavity (2) for performing single-crystallization on the anode target surface (11); step 2, fixedly placing the anode target (1) in the working cavity (2), and starting up the single-crystal fabrication device to melt the anode target surface (11), the melting temperature being 3360-4000°C; and step 3, cooling and condensing the molten anode target surface (11), so that the anode target surface (11) is in a single crystal state, a glass crystal, or a local single crystal. According to the process, the anode target surface (11) is changed from a polycrystalline state to a single crystal state, so that the definition and intensity of X-rays emitted by an X-ray tube are greatly improved, and the service life of the X-ray tube is effectively prolonged; moreover, the anode target surface (11) after single-crystallization has anti-evaporation properties, so that the accuracy of X-rays is effectively improved, and the accuracy of detection results of the CT machine is ensured. The process is suitable for being promoted for broad applications.
