Abstract
An X-ray tube anode comprises a graphite ring, a target substrate applied onto the graphite ring and a target focal track applied onto the target substrate. The target focal track comprises a first refractory metal and the target substrate comprises a second refractory metal and at least one layer of a material that is characterized by characterized by a coefficient of thermal expansion (CTE) that is the same as the CTE of the target focal track or is intermediate between the CTE of the target focal track and the CTE of the substrate.
Claims8
A process of making an X-ray tube anode having a target graphite ring, substrate and focal track, comprising:
- forming a portion of said target substrate on said graphite ring;
- applying a layer of a material having a CTE the same as a CTE of a material of said focal track or CTE intermediate between a CTE of a material of said substrate and said CTE of said material of said focal track;
- applying another portion of said target substrate onto said layer;
- and
- applying said focal track onto said substrate portions to produce said X-ray tube anode.
