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 ).
