Abstract

Für ein Verfahren zur Steigerung der Dämpfung eines Gußbauteiles aus einem Leichtmetallwerkstoff mit einem zusätzlichen, die Dämpfung steigernden Element wird vorgeschlagen, daß als Element eine aus einem derartigen Schwermetall oder einer Schwermetall-Legierung von großer Eigendämpfung gebildete und beim Gießen im wesentlichen vollständig infiltrierbare Draht-Textur als Gießeinlage verwendet wird, daß in den Verbindungsbereichen von Leichtmetall-Matrix und Schwermetalldrähten bei einem Energieeintrag (Schall, Körperschall) durch zu den Drähten längselastische Verformungen eine Steigerung der Materialdämpfung im Gußbauteil bewirkt wird.For a method for increasing the damping of a cast component from one Light metal material with an additional element that increases damping it is proposed that one of such a heavy metal or a heavy metal alloy of great self-damping and formed Casting essentially completely infiltrable wire texture used as a casting insert will that in the connection areas of light metal matrix and Heavy metal wires with an energy input (sound, structure-borne sound) through to the Wires with longitudinal elasticity increase the material damping in the Cast component is effected.
