Abstract
In the manufacture of rotating anodes for X-ray tubes consisting of a basic body made of high-melting metal or its alloys and one or a plurality of graphite parts, the graphite parts (3) are provided with grooves (5) and boreholes (6) before the individual parts are joined by soldering. The grooves (5) mainly having a semicircular cross section are provided in the surface (4) of the graphite parts (3) to be joined by soldering. The boreholes (6) extend through the graphite parts (3) and feed into the grooves (5) approximately vertical to the graphite surface (4). Excessive solder and gases formed during soldering may flow or escape by way of the grooves and boreholes, which produces an improved soldered joint with increased adhesive or bonding strength between the basic body and the graphite parts.
