Preparation method for anode target of X ray tube

The invention relates to a preparation method for an anode target of an X ray tube. A laser refusion technology is introduced to a plasma spraying technology, a metal coating is prepared in a multitime layered deposition manner, and the laser refusion effect is ensured. The density of the metal coating is improved, the intensity is improved, stress problems caused by laser refusion are reduced, disadvantages in the present technology are overcome, and the quality of the anode target of the X ray tube is improved. 种X射线管阳极靶的制备方法，该制备方法通过在等离子喷涂工艺中引入激光重熔工艺，并将金属涂层以多次分层沉积的方式制作，确保了激光重熔的效果。方面可以提高金属涂层的密度，增加强度，另方面有可以减少激光重熔带来的应力问题，从而克服了现有工艺中的缺点，使得X射线管阳极靶的质量得到提升。
