    摘要： An improved high performance x-ray system having a rotating anode therein which includes an improved target/stem connection and a coating, operatively positioned between the target and the stem, for enhancing the diffusion therebetween to reduce tube failure due to anode assembly imbalance comprising a metallic target and a metal stem bonded to provide a composite rotating x-ray tube target is disclosed. An insert of an alloy, for example, titanium alloy, is placed between the target layer, the stem and a coating, operatively positioned between the target and the stem, for enhancing the diffusion therebetween and then bonded thereto to produce a composite x-ray tube target/stem having a high remelt temperature and bond strength which retains its balance throughout the manufacturing process and during x-ray tube operations is also disclosed.
