摘要： An x-ray tube target has improved heat dissipation by applying a layer of diamond between the focal track and the target body. The diamond layer can be applied directly to a graphite target body, a graphite disc covered with silicon carbide or to a disc composed of an molybdenum alloy such as TZM.

摘要： A composite target for an x-ray tube has a graphite substrate portion and a metal portion, the two portions being bonded together by platinum and platinum alloying materials. The preferred alloying materials are tungsten and nickel which act in conjunction with the platinum to improve the bond resulting in an x-ray tube having a longer life span.

摘要： An x-ray imaging apparatus having an anode stem assembly with explosion-bonded joints is provided. Explosion-bonding the components of an anode stem assembly to one another provides a hermetic seal with increased reliability as well as reducing the anode stem's susceptibility to thermal and/or mechanical induced fracture. By eliminating the need for brazing and/or welding material within the anode stem, the present invention also provides an anode stem with increased heat transfer capabilities. Further, providing explosion-bonded joints creates a simple joint microstructure absent any voids and temperature-induced phases not previously present in the anode stem materials.
