Abstract
An improved high performance x-ray system having a rotating anode therein which includes an improved coating for the x-ray tube rotor. The surface of the x-ray tube rotor is coated with a ductile coating wherein at least about 40,000 x-ray scan-seconds are accomplished prior to tube failure due to spalling. The coating may be a ductile alloy such as Rene' 80 having a thickness of about 0.2 to about 5.0 mils thick and may be even thicker. The rotor coating 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.
