Abstract: In situ alloying of elemental Cu, Cr, and Nb powder using laser melting to form a Cu—Cr2Nb alloy. The elemental powders are initially mixed to form a homogeneous mixture, which mixture is then subjected to laser radiation to melt the mixture. In the melt, the Cr and Nb react to form Cr2Nb, which when cooled form precipitates that are dispersed in a nearly pure Cu matrix to thus dispersion strengthen the material. The methods can be used to additively manufacture a 3D component of Cu—Cr2Nb alloy using a selective laser melting machine.

Abstract: Scalable power processing units (PPUs) for Hall-effect thrusters (HETs) and terrestrial systems are disclosed. A technique for current estimation may be employed on each output of parallel isolated discharge supply modules (DSMs) to force proper current/load sharing between the DSMs. A flyback power supply may be used that performs the dual functions of a cathode keeper plasma ignitor and sustainer. The flyback power supply may be tuned for a high no-load direct current (DC) output voltage to achieve cathode keeper ignition rather than requiring a separate ignitor supply, which reduces circuit complexity. To address requirements for higher voltage DC ignition than are achievable with a flyback power supply alone, a supplemental DC ignitor may be placed in parallel with the flyback power supply of some embodiments. Such simplified PPU architectures may provide a high efficiency, low part count, scalable architecture suitable for more compact and lower cost system designs.
