Processing of Bulk MgB2 Superconductors by Coupling Laser Powder Bed Fusion and Spark Plasma Sintering Techniques
This article demonstrates the concept proof to manufacture parts of MgB<sub>2</sub> by Laser Powder Bed Fusion (L-PBF) coupled to Spark Plasma Sintering (SPS) by an optimization of the L-PBF and SPS conditions to limit the phase degradation and complete the sintering. Optimal L-PBF parameters were identified in order to obtain the material preforms with a minimal degradation of the MgB<sub>2</sub> phase, and then these preforms were sintered by SPS using an inert powder as matrix with a purpose to receive a mechanically more reliable product. Sintered samples show superconductivity state inherent for the raw material and demonstrate superconducting transition around 38 K according to the magnetic moment measurements.
