Abstract
An x-ray tube having a rotating anode structure which comprises a circular titantium, zirconium, molybdenum alloy target section bonded to a graphite disc. The target section is coated with hefnium carbide as a heat emissivity barrier. The thickness of the barrier is preferably in the range of 4.0-5.0 .mu.m.
Claims1
An x-ray tube rotating anode structure comprising in combination
- (a) a circular graphite body,
- (b) a circular titanium, zirconium, molybdenum, alloy target section disc concentrically bonded to said graphite body,
- (c) said target section disc having a peripheral axial rim surface,
- (d) and an exposed high heat emissivity hafnium carbide coating on said target section rim surface, said coating having a heat emissivity greater than that of said target disc,
- (e) said coating being further characterized by having a thickness from about 4.0 .mu.m to about 5.0 .mu.m and a heat emissivity which increases with an increase in its temperature.
