Plasma Shock: A Tool for Synthesis and Property Improvement of Superconductors

Resumo

The influence of the shock-wave action of plasma on the structure and properties of coatings of magnesium and boron on various ductile metals (copper, aluminum, tin) was studied in this work. Experiments were performed to investigate the capabilities of МgВ₂ synthesis from the powder mixture of Mg and B in a metal covering with optimization of the impact conditions. The constitution, the structure, and the properties of the prepared samples were studied. As a result, a sharp decrease in voltage was established at temperatures of 30–40 K across the Cu-Nb-MgB wire.
