Abstract
(DE)
Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung eines komplexen geometrischen Bauteils enthaltend Kohlenstoff oder Siliziumkarbid, das mit diesem Verfahren hergestellte Bauteil und dessen Verwendung. Das Verfahren zum Herstellen eines komplexen geometrischen Bauteils enthaltend Kohlenstoff oder Siliziumkarbid umfasst die folgenden Schritte: a) Bereitstellen eines Grünkörpers auf Basis von Kohlenstoff oder Siliziumkarbid, welcher mittels eines 3D-Druckverfahrens hergestellt worden ist, b) Nachverdichten des Grünkörpers mittels der chemischen Gasphaseninfiltration.
(EN)
The present invention relates to a method for producing a complex geometric component containing carbon or silicon carbide, to the component produced by said method and to the use thereof. The method for producing a complex geometric component containing carbon or silicon carbide comprises the following steps: a) providing a green body on the basis of carbon or silicon carbide, which has been produced by means of a 3D printing method, b) redensifying the green body by means of chemical vapor infiltration.
