Abstract

The invention relates to a powder metallurgical molded part having a disk or plate shaped main part (1) and a plurality of knob and/or ridge shaped elevations (2) which are adjacent to one another in a row direction (11) and thus form a row and which have a height (h1 h2) perpendicular to the base plane of the main part (1) each elevation having a cross section with two lateral flanks. The lateral flanks lead from an elevation (2) end contour (3) which is arranged externally in the height direction (8) into curved sections with a curve radius via rounded corner sections. The curve radius transitions into the surface contour (7) of the main part (1) and a straight flank section of the lateral flank or a lateral flank tangent that lies at the point where the rounded corner section transitions into the curved section is arranged at an inclination angle (a1 a1 ; a2 a2 ) relative to the main plane of the main part (1). At least two different inclination angles (a1 a1 ; a2 a2 ) are present on the same face (9 10) of the main part (1) the at least two different inclination angles (a1 a1 ; a2 a2 ) representing at least one first geometry (h1 r1 r1 R1 R1 a1 a1 ) and a second geometry (h2 r2 r2 R2 R2 a2 a2 ).
