Abstract
Official abstract text for this publication.
According to one embodiment, an X-ray tube device includes a cathode which emits electrons, an anode target which generates X-rays when the electrons emitted from the cathode collide therewith, a first tube portion, a second tube portion which forms a flow path of a coolant together with the first tube portion, and a protective film. The protective film covers an inner surface of the first tube portion, and is formed of hard gold.
First claim
Opening claim text (preview).
What is claimed is: 1. An X-ray tube device comprising: a cathode which emits electrons; an anode target which generates X-rays when the electrons emitted from the cathode collide therewith; a first tube portion having one end portion and another end portion including a bottom portion which is closed and joined to the anode target; a second tube portion located inside the first tube portion, having a first end portion where an inlet for taking in a coolant is formed and a second end portion which is opposed to the bottom portion and where an outlet for discharging the coolant to the bottom portion is formed, and forming a flow path of the coolant together with the first tube portion; and a protective film covering an inner surface of the first tube portion and formed of hard gold, wherein the hard gold contains gold of greater than or equal to 99 wt %, and any one of cobalt, nickel and chromium of less than or equal to 1 wt %, and the hard gold contains cobalt in a range of 0.3 to 0.4 wt %. 2. The X-ray tube device of claim 1 , wherein the coolant is a water-based coolant.
