Abstract

This research showed the possibility of applying iridium hafnium alloy for a bipropellant thruster chamber. It also revealed that the heat resistant temperature of iridium hafnium alloy with aluminizing exceeded almost 1600°C, and that the alloy had excellent resistance to oxidation. A chamber made of the iridium hafnium alloy with aluminizing was then manufactured and its endurance for almost 1600°C was demonstrated in the hot firing tests. Through these tests, this alloy could be a good candidate material for the chamber of a high performance thruster and could be provide several advantages for customers.
