GRAPHITE X-RAY TARGET ASSEMBLY AND METHOD OF MAKING SAME

摘要

An x-ray target assembly is formed by passing a rotary shaft (10) through the center hole (22) of a graphite disk (20) such that the back surface (24) of the disk rests on a flange part (12) of the rotary shaft and the front surface (26) is contacted by a nut (40) which engages with the tip of the rotary shaft. Annular brazing materials (61, 62, 63, 64) are placed adjacent contact areas where the disk contacts the rotary shaft and the nut such that braze joints are made to secure the disk with the nut and the rotary shaft. Grooves (45) may be formed on the surfaces of the nut and the flange part of the rotary shaft which contact the disk such that the brazing material can more efficiently fill the gaps between contacting surfaces.
