摘　　要：传统的X射线管旋转阳极是采用CVD法生产,原材料利用率低,产品性能差。采用粉末冶金法可以大幅度提升产品性能,但是由于钨钼粉末压制性能差异极大,导致钨钼结合强度不高,在压制烧结甚至在装管后使用的过程中都有钨钼分层的现象发生。研究了如何采用合适的过渡层材料,提升钨钼的结合强度,以提高射线管的工作性能。The conventional X-ray tube rotating-anode target is usually produced by CVD technology, in which the utilization rate of raw materials is less and the product performance is poor. Although the product performance can be greatly improved by powder metallurgy method, the great difference in compaction properties between tungsten powder and molybdenum powder results in a bad bonding strength, and leads subsequently to separate layers be- tween tungsten and molybdenum during pressing, sintering and even X-ray working. A transition layer was used to increase the bonding strength between tungsten and molybdenum, thus improve the working performance of X-ray tube.
