摘要： In one example, an x-ray target comprises a target track, a substrate, and an optional backing. The target track includes a base material and a grain growth inhibitor to reduce or prevent microstructure grain growth in the base material. The target track can be included as part of an x-ray tube anode, either of a rotary form or a stationary form.

摘要： A method for manufacturing x-ray tube parts, wherein metallic pieces are explosively bonded together to establish a high strength, stable union between them. The x-ray tube parts may then be milled from the bonded metallic pieces. The explosion bonding process creates only discrete intermetallic components in the joint region instead of a continuous, weakening intermetallic layer common in brazed joints. An explosion bond joint is characterized by a wavelike interface, thereby increasing surface area over which the components are bonded and further increasing bond integrity. Stems, rotor hubs, rotor sleeves, anodes, and other tube components may be manufactured using this method.
摘要翻译：一种制造X射线管部件的方法，其中金属片爆炸地结合在一起，以便在它们之间建立高强度，稳定的联合。然后可以将X射线管部分从结合的金属片上研磨。爆炸结合过程在接合区域中仅产生离散的金属间部件，而不是在钎焊接头中常见的连续弱化金属间层。爆炸接头的特征在于波纹状界面，从而增加部件结合在一起的表面积，进一步提高粘结完整性。阀杆，转子毂，转子套管，阳极和其他管部件可以使用这种方法制造。

摘要： Stationary x-ray target assemblies manufactured using a metal deposition process to form one or more metal layers of the target. In particular, the metal deposition process is used to form an x-ray target metal layer and/or a stress buffer zone on an x-ray target substrate. The stress buffer zone improves material properties of the metals and/or the bonding between the x-ray target metal layer and the substrate. Improved bonding between the x-ray target metal layer and the substrate also improves the heat dissipation properties of the stationary x-ray target assembly.

摘要： A bearing assembly suitable for use in conjunction with x-ray device having a rotating target anode and electron source disposed in an evacuated enclosure. The bearing assembly includes a shaft having a rotor hub to which the anode is mounted. The shaft cooperates with front and rear bearing rings to define front and rear races, and a spacer facilitates positioning of the bearing rings. Front and rear ball sets are confined in the front and rear races, respectively. A bearing housing receives the bearing rings, spacer, front and rear ball sets, and part of the shaft. Finally, a magnet is disposed near the front bearing ring to prevent escape of foreign matter from the bearings and to prevent ingress of foreign matter to the bearings. Consequently, the magnet serves to extend the life of the bearings and to prevent foreign matter related arcing of the target anode and electron source.
摘要翻译：一种适合与x射线装置一起使用的轴承组件，其具有设置在抽真空的外壳中的旋转目标阳极和电子源。轴承组件包括具有转子毂的轴，阳极被安装到该转子毂上。轴与前后轴承圈配合以限定前后座圈，并且间隔件有利于轴承环的定位。前球和后球分别限制在前后比赛中。轴承座接收轴承环，间隔件，前后球套和轴的一部分。最后，磁铁设置在前轴承环附近，以防止异物从轴承中逸出，并防止异物进入轴承。因此，磁体用于延长轴承的寿命并防止目标阳极和电子源的异物相关电弧。

摘要： The x-ray target assemblies have an oxide dispersion strengthened (ODS) refractory metal alloy substrate that is bonded to a carbon-containing heat sink. The x-ray target assemblies have excellent bonding between the substrate and the heat sink. The improved bonding is achieved by placing an oxide-free barrier layer between the ODS metal substrate and the heat sink. The oxide-free barrier layer minimizes or eliminates chemical reactions that would otherwise be possible between the dispersed oxides and the carbon-based heat sink during the manufacturing process. Preventing these undesired reactions while manufacturing the x-ray target assembly yields a device with improved bonding between the heat sink and the substrate, compared to devices manufactured without the barrier layer.
摘要翻译： X射线靶组件具有结合到含碳散热器的氧化物分散强化（ODS）难熔金属合金基底。 x射线靶组件在衬底和散热器之间具有优异的接合。通过在ODS金属基板和散热器之间放置无氧化物阻挡层来实现改进的接合。无氧化物阻挡层在制造过程中最小化或消除了在分散的氧化物和碳基散热器之间可能的化学反应。与制造没有阻挡层的装置相比，在制造x射线靶组件时防止这些不期望的反应产生了具有改进的散热器和衬底之间的结合的装置。

摘要： A composite stator is disclosed for use with rotationally driven apparatus, particularly high voltage x-ray tubes. The composite stator generally comprises a core, a plurality of motor windings, and a retaining band. The core is comprised of two or more core sections having slots defined therein for receiving the motor windings. The motor windings are wound through and between the slots of the core sections, after which the core sections are joined together to form the core. The core sections are maintained in an assembled configuration by the retaining band. The motor windings are interconnected to comprise the electromagnetic pole pairs of the composite stator, thereby allowing the stator to induce the rotation of the rotor assembly of the high voltage x-ray tube.
