A CASE OF BRUCELLA MELITENSIS ENDOCARDITIS IN A PATIENT WITH CARDIOVASCULAR IMPLANTABLE ELECTRONIC DEVICE


Initial experiments to regenerate the surface of plasma-facing components by wire-based laser metal deposition

Plasma-facing components (PFC) in nuclear fusion reactors are exposed to demanding conditions during operation.The combination of thermal loads, plasma exposure as well as neutron induced damage and activation limits the number of materials suitable for this application.Due to its properties, tungsten (W) is foreseen as plasma-facing material (PFM)
