An x-ray tube comprising:
- a cathode adapted to emit electrons;
- a bearing assembly comprising a bearing hub;
- a target assembly positioned to receive the emitted electrons, the assembly having a target hub coupled to the bearing hub at an attachment face, wherein the attachment face comprises a first material compressed against a second material;
- and
- a first anti-wear coating attached to one of the first material and the second material and positioned between the first material and the second material.
A method of fabricating an anode assembly for an x-ray tube comprising:
- applying a first anti-wear coating to one of a first material and a second material;
- and
- coupling an x-ray target to a bearing at an interface that is comprised of the first material and the second material.
An x-ray imaging system comprising:
- a gantry;
- a detector attached to the gantry;
- and
- an x-ray tube attached to the gantry, the x-ray tube comprising:
- a bearing having a bearing hub;
- a target having a target hub coupled to the bearing hub at a contact location;
- and
- a first anti-fretting coating;
- wherein the contact location comprises a first material attached to a second material, and wherein the first anti-fretting coating is attached to one of the first material and the second material at the contact location and is positioned between the first material and the second material.
