Formation of the Structure and Physicomechanical Properties of a Quasicrystalline Al–Cu–Fe Alloy upon Plasma Spraying
Quasicrystalline coatings prepared under various thermal conditions of spraying have been studied. Initial quasicrystalline powders with dispersion of 10–50 μm were prepared in a low-pressure arc discharge plasma. The ...
Low-temperature magnetic behavior of nanostructured ferrite compositions prepared by plasma spraying
Peculiarities of low-temperature behavior of the magnetic properties of disordered spinel ferrites, prepared by means of dilution with the P2O5 amorphizing agent and by rapid quenching, were investigated. A sharp increase ...
Particular Charactristics of the Synthesis of Titanium Nitride Nanopowders in the Plasma of Low Pressure Arc Discharge
The method of producing TiN nanopowders in the plasma of low pressure arc discharge in nitrogen atmosphere is discussed. The influence of gas pressure on nanopowder dispersion is studied. It is shown that the particles ...
Copper Oxide of Plasma-Chemical Synthesis for Doping Superconducting Materials
Properties of nanodispersed powder copper oxide, synthesized during arc sputtering of copper in a gas mixture of low pressure oxygen, were studied. It was shown that the particles possess nanometer size and narrow size ...
Structuring in Fast-Quenched Ferrite Compositions under Plasma Spraying
The influence of the quench rate on structuring in spinel ferrites has been studied. It has been found that, when the quench rate is increased, the equilibrium spinel structure gradually becomes disordered. At the first ...
