Abstract
Description
- - Rhenium zeigt gegenüber Metallkarbiden, insbesondere TaC, keine Zerset zung.
- - Rhenium besitzt eine höhere Emissivität als Wolfram, sodass selbst glatte Oberflächen stärker emittieren. Poröse Rhenium-Sinterschichten bleiben selbst dann noch wirksam, wenn sie aufgrund hoher Betriebstemperaturen zu einer glatten Fläche versintern.
- - Die Auftragung einer Rheniumsinterschicht ist kostengünstig im Vergleich zur Herstellung dendritischer Strukturen.
