Abstract

Using the plasma method of electric arc spraying in helium at pressure of 25 Torr, Mg–Al–C nanocomposites were obtained, which, when calcined, form hollow spherical nanoparticles of aluminum and magnesium dialuminate oxides with sizes of 20 and 80 nm, respectively, and aluminum nanoparticles with a size of 70 nm coated with an oxide layer. The latter ones presence in the electric arc soot is explained by the droplet material entrainment from the evaporating electrode surface. It is shown that the arc discharge is not effective for the formation of alloys of materials with significantly different saturated vapor pressures, but it can be effectively used to create nanoparticles with a shell-core structure.
