Abstract
1. Композиционный наноструктурированный порошок для нанесения покрытий методом холодного газодинамического напыления, частицы которого содержат металлическую матрицу и оксидный упрочнитель, отличающийся тем, что между металлической матрицей и оксидным упрочнителем выполнен плакирующий слой из пластичного порошка (например, алюминия) с образованием при последующем отжиге диффузионного слоя из интерметаллидов на границе металлической матрицы и плакирующего слоя, а также армированного поверхностного слоя при взаимодействии плакирующего слоя и оксидного упрочнителя, причем в качестве металлической матрицы используют порошок из стали, аналогичной по составу стали Гадфильда.2. Композиционный наноструктурированный порошок по п.1, отличающийся тем, что толщина плакирующего слоя составляет 4-8 мкм, а толщина диффузионного слоя - 0,6-1,2 мкм.3. Композиционный наноструктурированный порошок по п.1, отличающийся тем, что в качестве оксидного упрочнителя используют наночастицы фракции 10-100 нм.4. Композиционный наноструктурированный порошок по п.1, отличающийся тем, что объемная доля оксидного упрочнителя в плакирующем слое составляет 30-40%.1. Composite nanostructured powder for deposition by cold gas-dynamic spraying, the particles of which contain a metal matrix and an oxide hardener, characterized in that between the metal matrix and the oxide hardener there is a cladding layer of plastic powder (for example, aluminum) with the formation of a diffusion layer during subsequent annealing from intermetallic compounds at the border of the metal matrix and the cladding layer, as well as the reinforced surface layer, when interacting, I clad a layer and an oxide hardener; moreover, a powder of steel similar in composition to Hadfield steel is used as a metal matrix. 2. Composite nanostructured powder according to claim 1, characterized in that the thickness of the cladding layer is 4-8 μm, and the thickness of the diffusion layer is 0.6-1.2 μm. Composite nanostructured powder according to claim 1, characterized in that nanoparticles of a fraction of 10-100 nm are used as an oxide hardener. Composite nanostructured powder according to claim 1, characterized in that the volume fraction of the oxide hardener in the cladding layer is 30-40%.
