摘要
The X-ray tube has a vacuum housing in which a cathode and an anode are arranged. A diffusion barrier layer is applied on outer surface or inner surface of the vacuum housing. The hydrogen diffusion coefficient of diffusion barrier layer is lower than the hydrogen diffusion coefficient of vacuum housing. The maximum thickness of diffusion barrier layer is about 10mu m. The diffusion barrier layer is made of metal, metal alloy or metal oxide.
