Abstract
A method of bonding a metallic target layer and a graphite disk to provide a composite rotating X-ray tube target wherein a layer of vanadium, titanium, or their alloys is placed between the target layer and the graphite disk. The assembly is heated in a rapid manner through a temperature range as provided by a carbon-braze metal eutectic temperature and a braze metal melt temperature with continued heating to a temperature of 75.degree. C. above the melt temperature. The elevated temperature is maintained for about 5 minutes and then the assembly is cooled in a rapid manner through the temperature range. A composite X-ray tube target is produced having a high remelt temperature and bond strength.
