Abstract
A powder metallurgical molded part includes a disk or plate-like main body and a row of knob-shaped and/or ridge-shaped elevations in a row direction having a height perpendicular to a main plane of the main body and a cross section with side flanks leading from an outer end contour in height direction of the elevation via rounded corner portions into curved portions with a curve radius. The curve radius merges into the surface contour of the main body and a rectilinear flank portion or tangent of the side flank lying at the point where the rounded corner portion merges into the curved portion is disposed at an angle of inclination to the main plane. At least two different angles of inclination are on the same side of the main body and the at least two different angles of inclination represent at least first and second geometries.
