Abstract—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 coatings have been sprayed on copper rings using a swinging plasmatron. It is found that the
increase in the quenching rate of melt droplets increases the chemical homogeneity and leads to formation of
nanostructured formations. The precipitation of nanostructured grains (d < 100 nm) in the sprayed alloy
leads to an increase in the mechanical characteristics (hardness, deformation, and ductility) and can be considered
as an additional factor of hardening of the material.
