| description | The invention discloses a nano oxide dispersion strengthened copper-based composite material and a preparation method thereof, the preparation method comprises the following steps: Cu-Me atomized alloy powder (Me is any one or more of Cr, Y and Al), H2O and H2O2 are placed in a high-temperature and high-pressure reaction kettle for supercritical water oxidation reaction, and then composite powder is obtained after suction filtration and vacuum drying; the composite powder treated through the supercritical water oxidation technology is reduced, and Cu-MexOy composite powder is obtained; and the Cu-MexOy composite powder is subjected to compression molding, spark plasma sintering is carried out, and the block Cu-MexOy copper-based composite material is obtained. The preparation method has the advantages of being low in preparation temperature, short in process, environmentally friendly and low in cost, the oxide reinforcement phase in the prepared copper-based composite powder is in the nanoscale and is distrib |
