Abstract
Dissimilar brazing porous W and Mo using the Pd and Ti foils have been investigated in the study. Successful brazed joints are obtained from using the Pd filler foil. Brazed joints are fully dense and free of any intermetallic phase. Meanwhile, infiltration of the Pd-rich melt into the porous W substrate is trivial, limited below 30 μm for the specimen brazed at 1610 °C for 600 s. The application of Pd filler metal shows great potential in brazing porous W and Mo for impregnated dispenser cathode application. © 2011 Elsevier Ltd. All rights reserved.
