ABSTRACT:
An x-ray target assembly is formed by passing a rotary shaft through the center hole of a graphite disk such that the back surface of the disk rests on a flange part of the rotary shaft and the front surface is contacted by a nut which engages with the tip of the rotary shaft. Annular brazing materials 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 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.
