<p>An improved high performance X-ray system (20) having a rotating anode (56, 61, 58) therein which includes an improved coating (96) for the X-ray tube rotor. The surface (92) of the X-ray tube rotor is coated with a coating (96) wherein at least about 40,000 X-ray scan-seconds are accomplished prior to tube failure due to spalling. The coating (96) may be a ductile alloy having a thickness of about 0.2 to about 0.5 mils thick and may be even thicker. The rotor coating (96) has ductile properties with a strain to fail greater than 0.05 % and thermal expansion properties which when placed on an X-ray tube rotor, provides at least about 40,000 X-ray scan-seconds prior to tube failure due to rotor spalling.</p> |
