Resumo: | The Ni-Mo composite alloy, to be used in microwave vacuum tube manufacturing, was prepared from metal powders previously homogenized, pressed and sintered at 1200oC by induction heating. The Ni-Mo sintered discs were annealed at 1150oC for 20min, and submitted to the roller process in 5 cycles to obtain a thin foil with 0.10 mm of thickness, for brazing process adopted to join the cathode components. The samples were submitted to scanning electron microscopy (SEM) coupled to energy dispersive spectroscopy analysis (EDS) to characterize the composition and microstructure. X-ray diffraction (XRD) was performed to determine the crystalline structure and energy dispersive X-ray fluorescence spectroscopy (EDX) was performed to determine the chemical composition and the homogeneity of the composite alloy. |
