Abstract

Die verschlossene, unter statischem Druck stehende Gießform wird anschließend gerichtet vibriert. Mit der Vibrations- bzw. Krafteinleitungsrichtung (V), die durch die Lage der Gießform relativ zur Vibrationsrichtung bestimmt wird, kann die Verteilung der Oberflächen- und Volumenfehler (Lunker) im Bauteil (K) gesteuert werden. Die Krafteinleitungsrichtung (V) ist dabei derart zu wählen, dass sie in Richtung der Oberflächennormalen (N) der qualitätskritischen Bauteilfläche - hier der Heißgasseite (HS) der Feuerfestkeramik - wirkt. Somit kann hier eine nahezu lunkerfreie Oberfläche der Heissgasseite (HS) der Feuerfestkeramik für Gasturbinenanlagen erreicht werden.

The sealed, static pressure mold is then vibrated directionally. With the vibration or force introduction direction (V), which is determined by the position of the mold relative to the direction of vibration, the distribution of surface and volume defects (voids) in the component (K) can be controlled. The force introduction direction (V) is to be selected such that it acts in the direction of the surface normal (N) of the quality-critical component surface - here the hot gas side (HS) of the refractory ceramic. Thus, a virtually void-free surface of the hot gas side (HS) of the refractory ceramic for gas turbine plants can be achieved here.
