Abstract

Cost-effective net-shaped forming components have brought considerable interest into the Department of Defense, the National Aeronautics & Space Administration, and the Department of Energy. Electron beam-physical vapor deposition (EB-PVD) offers flexibility in forming net-shaped components with tailored microstructure and chemistry. High-purity rhenium components, including rhenium-coated graphite balls and rhenium plates and tubes, have been successfully manufactured by EB-PVD. EB-PVD rhenium components exhibited submicron and nano-size microstructure with high hardness and strength as compared with chemical vapor deposition (CVD). It is estimated that the cost of rhenium components manufactured by EB-PVD would be less than the current CVD and powder-high-temperature isostatic pressure technologies.
