NANOSTRUCTURAL RAW MATERIALS FOR THERMIC DEPOSITION

摘要

FIELD: processes for making nanostructural materials used for deposition of nanostructure coating by means of standard installations for thermic deposition. SUBSTANCE: in one variant of invention nanostructural raw material contains spheric agglomerates prepared by secondary treatment of powders. In other variant of invention fine dispersion of nanoparticles is directly injected to torch or plasma in thermic deposition apparatus for applying nanostructural coatings. In next variant of invention liquid metallorganic chemical precursors are directly injected to torch of plasma apparatus for thermic deposition. In the result synthesis of nanoparticles, melting and hardening are realized during one operation. In all variants ultrasound is used for disintegrating particle-synthesized agglomerates, for dispersing nanoparticles in liquid medium and for spraying liquid precursor. EFFECT: production of nanostructural materials with ultrafine grains and particles suitable for thermic deposition. 22 cl, 5 dwg, 8 ex
