A rotating X-ray anode for generating X-radiation has an annular main body made of carbon-based material, an annular focal track covering, which is arranged on a focal track side of the main body, and a metal connection component, which is arranged radially inside relative to the main body. A radially outer portion of the connection component is formed by a tubular metal adapter. The radial outside surface of the adapter is at least partly joined, face to face and integrally, to at least a portion of the radial inside surface of the main body. An integral joining zone between the main body and the adapter extends over at least 75 percent of the area of the radial inside surface of the main body.

Rotating x-ray anode

An anode with a linear main direction of extent for an x-ray device, has an anode body and a focal track layer, which is connected to the anode body in a material-bonding manner on a focal track layer volume portion of the anode body. At least one cooling channel for the cooling of the anode body and the focal track layer is arranged in the interior of the anode body and at least the focal track layer volume portion is formed of a material with at least a basic matrix of refractory metal. The focal track layer volume portion extends as far as to the cooling channel.

Anode having a linear main extension direction

A shaped part that is particularly suited as an interconnector or an end plate for a fuel cell stack, is produced by pressing and sintering a pulverulent starting material. The shaped part has a basic body with a multiplicity of knob-like and/or ridge-like elevations with a height h. Each elevation has two inclined side flanks which lead, proceeding from an end contour of the elevation, via rounded corner portions, directly or via intermediate rectilinear portions, into curved portions with a radius R or R', which in turn merge into the surface contour, of the basic body. A ratio of the radius R:h or R&#x2032;:h ranges from 0.25, or preferably from 0.5 to 1.

Method of producing a shaped part

The shaped part has a basic body with a multiplicity of knob-like and/or ridge-like elevations with a height h. Each elevation has two inclined side flanks which lead, proceeding from an end contour of the elevation, via rounded corner portions, with a radius r or r' directly or via intermediate rectilinear portions, into curved portions, with a radius R or R&#x2032;, which in turn merge into the surface contour, of the basic body. The rectilinear portions, or, in the case of a direct transition of the rounded corner portions into the curved portions, the tangents at the point of the transition, have an angle of inclination relative to the surface contour, between 95&#xb0; and 135&#xb0;.
