Abstract
An electrodeposition process is used to manufacture a thin layer of iridium (212) on a mandrel. A Controlled Atmosphere Plasma Spray (CAPS) process is used to fabricate a rhenium, rhenium containing alloy, or refractory alloy layer (210) on the electrodeposited iridium layer (212). After deposition of rhenium, rhenium containing alloy, or refractory alloy, the process uses a second CAPS process to apply a transition refractory material (214, 216), such as niobium, at each end of a rocket engine chamber (200). The electrodeposited iridium layer (212) provides a highly purified, highly ductile, uniform iridium layer (212).
