Abstract
A structure which is resistant to corrosion at high temperatures comprises a ductile layer of a platinum group metal, such as iridium, and a layer of a refractory metal having a high strength at high temperatures, such as rhenium. A solid solution of the two metals is present between and metallurgically bonded to the two metal layers. Further, the structure may include a layer of ceramic such as zirconia or hafnia on the exposed face of the platinum group metal layer.
